Overview
/ OVERVIEWMPS-8A8R-S is an industrial PLC controller with 8 isolated digital inputs and 8 relay outputs. Onboard RS-485, I²C, programmed in MP STUDIO ladder logic. DIN-rail mountable for automation, testing, HMI integration and machine control.
Key features
- Programmed in MP STUDIO ladder logic
- 8 opto-isolated digital inputs (NPN/PNP, up to 40 V tolerant)
- 8 relay outputs for AC/DC dry-contact switching
- 4 analog inputs (0–5 V / 4–20 mA / 0–10 V ranges)
- 2 NTC temperature inputs (−40 to +120 °C)
- Industrial communication: RS-485, I²C · Modbus RTU
- DIN-rail 35 mm mountable, isolated field I/O for the factory floor

Field wiring, COM grouping, and the full contact list for the MPS-8A8R-S are documented in the user manual (download below). I/O is addressed by contact name (P0…, P32…, AI0…, PWM0…). Digital inputs are opto-isolated and accept NPN or PNP sensors depending on COM wiring; outputs and analog ranges follow the terminal layout in the manual.
Software
MP STUDIO — Ladder Logic
The MPS series is programmed in MP STUDIO, a free ladder-logic IDE. Draw the control logic as a ladder diagram and call analog, temperature, high-speed counter and pulse output straight from function blocks.

Before the first download
Install MP STUDIO from the ILOGICS download centre, pick your model in the device list, set the COM port, and you can download straight away.
Models that use the MP download cable appear in Device Manager as "USB Serial Port". If it does not appear, install the FTDI driver as well.
