FX3U-14MR / 14MT PLC — Compact 8 Input 6 Output Controller

The FX3U-14MR / 14MT PLC is a Mitsubishi FX3U-compatible programmable logic controller built for compact industrial automation. It delivers 8 digital inputs and 6 digital outputs in a space-saving panel-mount body, with integrated 6 analog inputs and 2 analog outputs (6AD/2DA), a real-time clock (RTC) and MODBUS RTU protocol support. RS485 communication is optional (RS232 is default; choose RS485 when ordering). Program it easily with GX Works2 (also GX Developer). Choose 14MR for relay outputs (5 A per point, AC/DC loads) or 14MT for transistor outputs (1 A per point, high-speed PWM).

6 Key Features

8 Input / 6 Output — space-saving 14-point design for compact control panels.
6AD / 2DA Analog I/O — AD0–AD2 0–10 V, AD3–AD5 0–20 mA; 2DA 0–10 V analog output for precise process control.
Real-Time Clock (RTC) — enables time-stamped logging and scheduled automation tasks.
Optional RS485 Communication — add RS485 for long-distance multi-device networking (RS232 default).
MODBUS Protocol — seamless integration with HMIs, inverters, sensors and SCADA systems.
Program with GX Works2 — standard Mitsubishi programming environment; also supports GX Developer.

FAQ

Q: What is the difference between FX3U-14MR and 14MT?
A: 14MR uses relay outputs (5 A/point) for AC/DC loads and accepts 24 V or 220 V input; 14MT uses transistor outputs (1 A/point) for high-speed PWM and accepts 24 V DC input.

Q: Which software programs the FX3U-14MR/14MT?
A: It is programmed with Mitsubishi GX Works2 (and GX Developer), the standard FX3U development environment.

Q: Does FX3U-14MR/14MT support RS485 and MODBUS?
A: Yes. MODBUS RTU is supported. RS232 is default; RS485 is optional and can be selected when ordering.

Q: How many analog channels does it have?
A: It integrates 6 analog inputs and 2 analog outputs (6AD/2DA) for temperature, pressure and speed signals.
