Mitsubishi Electric FX1S-30MR-ES/UL Programmable Logic Controller

The Mitsubishi Electric FX1S-30MR-ES/UL is a compact programmable logic controller (PLC) designed for reliable logic processing and compact machine control in small automation setups. It features 30 total I/O points (16 inputs, 14 outputs) with digital DC (24 V, sink/source) inputs and relay outputs rated about 2 A per point, powered from 100–240 VAC, and it mounts on a DIN rail. Programming uses ladder logic with 2000 steps of program memory, and optional RS-232/RS-485 communication via an expansion board to integrate with sensors and actuators. It offers high-speed counting up to 60 kHz (single phase), consumes roughly 21 W, and has an IP10–IP20 protection class, operating from 0 to 55 °C with storage from -20 to 75 °C; common applications include small production machines, conveyors, packaging equipment, HVAC control, and material handling systems that require dependable, straightforward control. Common replacements: Mitsubishi FX3S-30MR/ES; Siemens LOGO! 12/24RCE; Allen-Bradley MicroLogix 1000 (1761-L32BWA).
