The FX5U-32MR/ES is part of the MELSEC iQ‑F FX5U series, combining AC power supply, CPU, and 32 digital I/O in one compact base unit suitable for packaging, material handling, HVAC, and general OEM machines. It provides 16 integrated 24V DC digital inputs (sink/source) and 16 relay outputs (2A at 250V AC), giving flexible wiring options for a mix of sensors and actuators. With 64K steps of FLASH program memory and a 34ns LD/MOV instruction execution time, the FX5U‑32MR handles complex logic, positioning, and communication tasks while maintaining short scan times.
Built‑in standard features include 2 analog input channels, high‑speed counters, pulse outputs, hardware pulse‑width measurement, and input interrupts, enabling precise motion and process control without extra special modules. Communication is a major strength: one Ethernet port (MODBUS/TCP, MC protocol, CC‑Link IE Field Basic, MELSOFT connection) and at least one RS‑485 port (MODBUS RTU/ASCII) are integrated, and the local system can be expanded up to 256 local and 512 total local+remote I/O points using FX5U‑compatible expansion and special function modules. The unit is DIN‑rail or panel mountable, with 100–240V AC supply, 30W power consumption, IP10–IP20 protection, and a 0–55°C operating range that meets IEC 61131‑2 requirements.
