MPA-48A48R

MPA Series is an assembled industrial PLC combining a CPU module with digital input and output modules.
Analog input/output, temperature sensor input, and high-speed pulse output modules can be added as options.
The selected I/O and optional modules are assembled and shipped as one product. Users cannot add or remove modules.

MPA-48A48R provides 48 digital inputs and 48 relay outputs.

Program with ladder logic using MP STUDIO.

Digital inputs

See the one-channel digital-input check before wiring for the first time. →

Module	Group	Input contacts	Input configuration
Module 0	COM0 COM1	P0~P3 P4~P7	8 isolated digital inputs 4 points/1COM
Module 1	COM0 COM1	P8~P11 P12~P15	8 isolated digital inputs 4 points/1COM
Module 2	COM0 COM1	P16~P19 P20~P23	8 isolated digital inputs 4 points/1COM
Module 3	COM0 COM1	P24~P27 P28~P31	8 isolated digital inputs 4 points/1COM
Module 4	COM0 COM1	P32~P35 P36~P39	8 isolated digital inputs 4 points/1COM
Module 5	COM0 COM1	P40~P43 P44~P47	8 isolated digital inputs 4 points/1COM

The diagram shows a wiring example for module 0. For other modules, use the corresponding contact numbers in the table. This example uses a DC 24V supply; each group can use PNP or NPN depending on its COM wiring.

The digital inputs are isolated by optocouplers. NPN or PNP switches and sensors can be used depending on the COM terminal wiring of each input module.

Relay outputs

See the one-channel relay-output check before wiring for the first time. →

Module	Group	Output contacts	Contact configuration
Module 0	COM0 COM1	P64~P67 P68~P71	8 relay outputs 4 points/1COM
Module 1	COM0 COM1	P72~P75 P76~P79	8 relay outputs 4 points/1COM
Module 2	COM0 COM1	P80~P83 P84~P87	8 relay outputs 4 points/1COM
Module 3	COM0 COM1	P88~P91 P92~P95	8 relay outputs 4 points/1COM
Module 4	COM0 COM1	P96~P99 P100~P103	8 relay outputs 4 points/1COM
Module 5	COM0 COM1	P104~P107 P108~P111	8 relay outputs 4 points/1COM

The diagram shows a wiring example for module 0. For other modules, use the corresponding contact numbers in the table.

Relay outputs are dry contacts. When ON, the corresponding output contact connects to COM.

Optional modules

Module	Maximum points	Function
Analog inputs	20 points	DC 0~5V, DC 0~10V, 0~20mA or NTC temperature sensor input
PT100Ω temperature sensor input	20 points	2-wire or 3-wire PT100Ω temperature sensor input
Analog outputs	12 points	DC 0~5V, DC 0~10V or 0~20mA output
High-speed pulse outputs	12 points	Pulse output up to 1MHz

Communication and program upload

Function	channel	Terminals / Ports	Usage
Program upload and monitoring	-	DOWNLOAD	Select as download port in MP STUDIO
RS-232	Channel 1	TX, RX, GND	Use MP STUDIO communication port settings
RS-485	Channel 2	485+, 485-	Use MP STUDIO communication port settings
UART	channel 3	TXD, RXD, GND	Use MP STUDIO communication port settings
I²C	1 channel	SDA, SCL	Master communication

The I²C diagram shows a connection example for a 5V device. Check the other device's signal voltage before connecting UART.

Status LED

Control the CPU module STATUS LED with the @SLED contact in MP STUDIO.

Development environment setup

Connect the computer to the CPU module DOWNLOAD port with a USB cable.
Check the download port's COM number in Device Manager.
In MP STUDIO, open the MPA tab and select MPA-48A48R(T).
Set the verified COM number as the download port, then download the ladder program.
