-====== I/O Wiring Guidelines ======
+====== First wiring and I/O check ======
-Incorrect wiring can damage the product or cause equipment malfunction. Always consult both the manual and terminal diagram for the selected product.
+This guide explains how to connect power, a sensor, or a load to an ILOGICS product for the first time. **Power terminals, COM groups, signal ranges, and ratings vary by model. Keep the detail page for your exact model open while following these steps.**
-===== General Procedure =====
+===== 1. Find your product =====
-  - Disconnect all power sources.
+Read the model name on the product label, then open the matching product family. In the output portion of a model name, **R identifies relay outputs** and **T identifies SINK transistor outputs**. A model containing both, such as MPINO-16A8R8T, provides both output types. Their wiring is different.
-  - Check the model, terminal names, power polarity, and COM groups.
-  - Check input-signal and output-load ratings.
-  - Set the DIP switches and jumpers.
-  - Disconnect the load and first check the program and a single I/O channel.
-  - Connect the final load and test interlocks and emergency stops.
-===== Digital inputs =====
+^ Product family ^ Configuration and detail pages ^
+| [[:en-us_products:mpino_series|MPINO Series]] | An industrial Arduino with I/O and communication circuits on one PCB. Select the model from the product table. |
+| [[:en-us_products:mpaino|MPAINO Series]] | An industrial Arduino assembled from a CPU and I/O modules. Check the model and installed option modules. |
+| [[:en-us_products:mps|MPS Series]] | An all-in-one PLC programmed with MP STUDIO. Select the model from the product table. |
+| [[:en-us_products:mpa|MPA Series]] | A modular PLC programmed with MP STUDIO. Check the model and installed option modules. |
+| [[:en-us_products:mnet|MNET Series]] | Remote I/O controlled by a Modbus RTU or LS Electric Cnet master. Check the ordered protocol and model. |
-MPAINO digital input modules pass DC 5~24V signals to the MCU through optocouplers and include pull-down resistors. Use ''INPUT'' in software.
+On the model page, first open **Power**, **Digital inputs**, and either **Relay outputs** or **Transistor outputs**. The analog, temperature, and high-speed sections on the same page show the terminals and operating conditions for those functions.
-MPINO input terminals, COM groups, and NPN/PNP wiring support may vary by model. Check the manual for your product.
+===== 2. Check before wiring =====
-===== Relay outputs =====
+{{ :guide:first-wiring-flow-en.svg?1000 |Sequence from identifying the product to checking one channel }}
-Relay outputs open and close load circuits through separate contacts.
+{{ :guide:first-wiring-flow-en-mobile.svg?350 |Mobile diagram of the first-wiring sequence }}
-  * Do not equate the relay component's maximum rating with the current limits of the product terminals and COM.
+  - Disconnect **all power** from the product, sensor, and load.
-  * Account for inrush current and back EMF from motors, solenoids, and contactor coils.
+  - On the model page, locate the power terminals and polarity, the channel you will use, and that channel's COM group.
-  * Consider a diode for DC coils, and a suitable snubber or protective device for AC loads.
+  - Check the sensor output type, load voltage and current, and the product's per-point and per-COM ratings.
-  * Do not rely solely on one relay and the program to disconnect loads affecting personal or equipment safety.
+  - If the function has DIP switches or jumpers, set them with power off exactly as shown on the model page.
+  - Wire one channel first. Pull each conductor lightly to confirm it is secure and make sure no bare conductor extends outside the terminal.
+  - Inspect the wiring again, apply the power specified for the product, and check the indication and program value for that channel.
-===== Transistor outputs =====
+See [[:en-us_safety|Safety and installation precautions]] for power, grounding, protective circuits, and the work environment.
-MPAINO transistor outputs use an **N-CH FET SINK configuration**.
+===== 3. Digital input one channel check =====
-<code>
+A digital input turns ON when current flows between the input terminal and the COM assigned to that input. On products that support both NPN and PNP inputs, the COM connection selects the input arrangement.
-External supply (+) ── Load ── Output terminal
-External supply (-) ───────── COM/GND
-</code>
-The output terminal is not a voltage source. Check the external supply, load polarity, and COM wiring. Add back-EMF protection for inductive loads.
+{{ :guide:first-wiring-digital-input-en.svg?1000 |Current paths for PNP and NPN digital inputs }}
-===== Analog Input X =====
+{{ :guide:first-wiring-digital-input-en-mobile.svg?350 |Mobile current-path diagram for PNP and NPN inputs }}
-The MPAINO X module uses ADS1118. Select one of the following input types with the DIP switches.
+The diagram shows the operating principle for a product that supports both NPN and PNP inputs. **Use the digital-input section for your model as the authority for input voltage, terminal names, COM groups, and supported wiring.**
-  * DC 0~5V
+  - On the model page, choose one input and identify its assigned COM.
-  * DC 0~10V
+  - Confirm whether the sensor output is PNP or NPN, then use the matching diagram on the model page.
-  * 0~20mA
+  - With power off, connect sensor power, the output wire, the input terminal, and COM.
-  * NTC temperature sensor
+  - Inspect the wiring again, apply power, and operate the sensor.
+  - If the model has an input indicator, confirm that it changes. Then confirm the same input address in the program or communication master.
-Turn off the power before setting DIP switches to change the input type. Do not connect a current signal to a voltage input or configure the reverse combination.
+^ Result ^ What to check next ^
+| The indicator and program value both change | The one-channel check is complete. Check the remaining inputs the same way. |
+| The input indicator does not change | Recheck sensor power, output type, input voltage, input terminal, and COM wiring. |
+| The indicator changes but the program value does not | Check that the program input number or MNET communication address matches the physical channel. |
-===== Analog Output Y =====
+For MPINO and MPAINO, use the [[:en-us_guide:getting_started#control_the_output_with_the_first_input|first-input Arduino IDE example]]. For MPS and MPA, use the input example on the selected model page and the MP STUDIO monitor. For MNET, use **Default I/O communication addresses** and **Communication startup procedure** on the model page.
-The Y module smooths MCU PWM into a DC signal. Select 0~5V, 0~10V, or 0~20mA output with the DIP switches. Before connecting, check the receiving equipment's input type, common potential, and load conditions.
+===== 4. Relay output one channel check =====
-===== PT100 Input F =====
+When a relay output turns ON, the output terminal and its assigned COM are connected by a contact. The contact does not generate load voltage, so **the external circuit must supply power to the load.**
-The F module uses ADS1118 and accepts 2-wire or 3-wire PT100 sensors. Check sensor wiring and terminal order in the module manual.
+{{ :guide:first-wiring-output-en.svg?1000 |Comparison of relay and SINK transistor output current paths }}
-===== Communication Wiring =====
+{{ :guide:first-wiring-output-en-mobile.svg?350 |Mobile comparison of relay and SINK transistor outputs }}
-RS-232, RS-485, and TTL UART have different electrical specifications. Do not connect them directly to one another merely because they are all serial interfaces. For RS-485, review A/B polarity, termination, grounding, and communication settings across the entire system.
+  - On the model page, identify one output, its COM, and the per-point and per-COM ratings.
+  - Turn off all power and connect the external supply, load, output terminal, and COM as shown in the model wiring diagram.
+  - For motors, solenoids, and contactor coils, check normal current, inrush current, and the required back-EMF protection.
+  - Inspect the wiring again. Turn one output ON and OFF, then check the output indicator, relay operation, and load in that order.
-[[:en-us_safety|View All Safety Precautions →]]
+Do not use the relay component's maximum rating as the terminal or COM rating of the finished product. Use a separate safety circuit for loads related to personal or equipment safety.
+===== 5. SINK transistor output one channel check =====
+When a SINK transistor output turns ON, it connects the output terminal toward the negative side of the supply so load current can flow. The output terminal does not provide the load voltage by itself.
+  - On the model page, check the output, output-power terminals, load voltage, and per-point and per-COM current ratings.
+  - If the model has output-power terminals such as P24 and N24, connect them with the polarity shown in its wiring diagram. Terminal names vary by model.
+  - With power off, connect a single path through supply positive, the load, the output terminal, and supply negative.
+  - Inspect the wiring again, then turn one output ON and OFF and check the output indication and load.
+Measuring only between the output terminal and GND can give a misleading result. The external supply, load, and negative common must all be connected for current to flow.
+===== 6. Check an analog input =====
+Even when terminals look alike, an analog input may be configured or ordered for voltage, current, or NTC input.
+{{ :guide:first-wiring-signal-map-en.svg?1000 |Where to check analog, temperature, and high-speed signal wiring }}
+{{ :guide:first-wiring-signal-map-en-mobile.svg?350 |Mobile map for analog, temperature, and high-speed signals }}
+  - On the model page, confirm the input type and range for the channel you will use.
+  - If the module has DIP switches, turn off power and select the required input type.
+  - Check the source range, signal conductor, and signal common, then connect one channel.
+  - Select the same channel and input type in the program example and confirm that the raw or scaled value follows the signal.
+For MPAINO, see [[:en-us_products:mpaino_x|Analog Input X Module details]]. For MPA, see [[:en-us_products:mpa_x|Analog Input X Module details]].
+===== 7. Check an analog output =====
+First distinguish a built-in analog output from a Y option module, then identify whether the receiving equipment accepts voltage or current input.
+  - On the model page, check the output channel, signal range, common, load conditions, and any required external power.
+  - If the module has DIP switches, turn off power and select the required output type.
+  - Confirm that the receiver uses the same input type, then connect one channel.
+  - Start with a low output value within the receiver's permitted range, increase it in steps, and check the measured value or receiver display.
+For MPAINO, see [[:en-us_products:mpaino_y|Analog Output Y Module details]]. For MPA, see [[:en-us_products:mpa_y|Analog Output Y Module details]].
+===== 8. Check PT100 and NTC temperature inputs =====
+PT100 and NTC sensors have different characteristics and wiring. They are not interchangeable.
+^ Sensor ^ Check first ^
+| NTC | Check the specified NTC characteristic, built-in pull-up, sensor terminal, and signal common. Also distinguish a built-in NTC input from an X-module NTC input. |
+| PT100 | Identify a 2-wire or 3-wire sensor and follow the channel terminal order on the F-module detail page. |
+For MPAINO, see [[:en-us_products:mpaino_f|PT100 Temperature Input F Module details]]. For MPA, see [[:en-us_products:mpa_f|PT100 Temperature Input F Module details]].
+If the temperature is outside the displayed range, first check the sensor type, open circuits, terminal order, and selected program channel.
+===== 9. Check high speed pulses and encoders =====
+High-speed inputs and pulse outputs can have different voltage, maximum frequency, and hardware-resource requirements from ordinary digital I/O. Some models share resources with I²C, analog output, or another pulse channel.
+  - On the model page, identify whether the terminal is a high-speed counter input, encoder A/B phase input, or pulse output.
+  - Check input or output voltage, maximum frequency, pull-up or pull-down, and isolation.
+  - Check for communication, analog-output, or timer functions that cannot be used at the same time.
+  - Verify counting or output on one channel at a low frequency, then increase it to the required frequency.
+For MPAINO, see [[:en-us_products:mpaino_k|High-Speed Pulse Output K Module details]]. For MPA, see [[:en-us_products:mpa_k|High-Speed Pulse Output K Module details]].
+===== 10. Troubleshooting =====
+^ Symptom ^ Check first ^
+| Product does not power on | Check the supply voltage, power terminals, polarity, and required power-supply capacity on the model page. |
+| Input does not change | Check sensor power and output type, input terminal, assigned COM, input voltage, and program address. |
+| Relay operates but the load does not | Check the external load supply, COM paired with the output, an open load circuit, and protective devices. |
+| Transistor output does not operate | Check SINK wiring, output-power terminals, supply positive and negative, load polarity, and program address. |
+| Analog value remains at zero or full scale | Check the input type and DIP setting, signal range, channel, signal common, and open circuits. |
+| Analog value fluctuates continuously | Check power and grounding, shielding and cable routing, source stability, and the model's recommended power conditions. |
+| Temperature is outside the expected range | Check PT100 or NTC type, 2-wire or 3-wire wiring, terminal order, and an open sensor. |
+| High-speed count is incorrect | Check input voltage and waveform, maximum frequency, edge setting, common, and shared functions. |
+Change one item at a time in this order: **power → COM → one channel → program address**.
