Mitsubishi Electric FX2N-48ER-ES/UL Relay Output Module

The Mitsubishi Electric FX2N-48ER-ES/UL is a 48-point relay output I/O expansion module for the FX2N PLC series, designed to extend a controller’s capacity to drive external devices and actuators in industrial automation systems. It provides 48 relay outputs (Form A/CO contacts) with backplane bus communication to the host PLC and is UL-listed with CE certification. Key specs include output voltage up to 250 VAC / 30 VDC (model dependent), typical 2 A per point (model dependent), optical or safe isolation from PLC logic, power supplied via the host PLC power system, and mounting options on DIN rails or in PLC racks. Operating temperature range is 0 °C to 55 °C with storage from -25 °C to 75 °C, and protection class IP20. Common replacements include Mitsubishi FX3U-32ER/ES-A, Siemens SM 322-2 (model dependent), and Allen-Bradley 1769-OB32 (relay output module). Common applications span conveyor systems, manufacturing automation, packaging equipment, process machinery, and material handling systems where reliable relay control of multiple actuators is required.
