The Mitsubishi FX5-485ADP module is an RS-485 communication module designed as an FX5U PLC adapter, enabling reliable industrial network connectivity for data exchange with external devices via high-speed serial communication.

Specification

SEODescription

The Mitsubishi FX5-485ADP module is an RS-485 communication module designed as a compact adapter for FX5U PLC systems, enabling seamless integration with industrial networks. While the module itself does not feature analog or digital I/O points, it directly connects to the FX5U PLC via a dedicated port and supports up to 16 slave devices in a single RS-485 network. It operates on 24V DC (±10%) and functions reliably within 0–55°C (operating) and -25–75°C (storage). Ideal for automation, manufacturing, and process control, this adapter excels in environments requiring stable long-distance communication (up to 1.2 km) using protocols like Modbus RTU. Key advantages include robust noise immunity and easy configuration via GX Works3 software, though its lack of built-in isolation and dependency on FX5U PLCs may limit flexibility in mixed-platform setups.
