Specification

SEODescription

The Mitsubishi FX5-16ER/ES Module is a compact FX5U PLC Expansion Unit designed to extend digital I/O capabilities in automation systems. It integrates 16 digital inputs (24VDC sink/source) and 16 transistor outputs (sink type) for direct interfacing with sensors, switches, and actuators. Compatible with MELSEC FX5 Digital I/O systems, it supports direct connection of up to 16 expansion modules via a built-in high-speed bus, enabling scalable configurations. The module operates at 24VDC ±10% with a temperature range of 0–55°C, suitable for industrial environments like manufacturing, packaging, and process control. Communication interfaces include Ethernet, RS-485, and CC-Link for seamless integration. Key advantages include high-speed response (0.1ms), compact design, and compatibility with GX Works3 programming. Limitations include lack of analog I/O support and dependency on the main FX5U CPU for operation. Its rugged construction ensures reliability in harsh conditions.
