FX5U-32MR/ES 32 I/O PLC CPU Unit 16DI/16DO Relay | Mitsubishi Electric

The Original New Mitsubishi Electric FX5U-32MR/ES is a compact programmable logic controller (PLC) CPU unit from the MELSEC iQ-F series, designed for high-speed machine control and industrial automation. Featuring 16 digital inputs (24 V DC, sink/source), 16 relay outputs, and 64K steps (128 KB) flash program memory, it delivers 34 ns per instruction processing speed. Built-in Ethernet and RS-485 ports, analog I/O, high-speed counters, and positioning functions reduce the need for additional modules, making it suitable for packaging, material handling, and OEM machinery applications.

Core Engineering Highlights:
16 digital inputs (24 V DC, sink/source) | 16 relay outputs | 64K steps (128 KB) flash program memory | 34 ns/instruction processing speed | Built-in Ethernet (1 port) + RS-485 (1 port) | Built-in analog I/O: 2 inputs + 1 output | Up to 6 high-speed counters (200 kHz) + 2 (10 kHz) | Positioning: up to 4 axes at 200 kHz | 256 local I/O / 512 with remote I/O | 100–240 V AC power supply | 150 mm width
