Mitsubishi Electric FX2N-32ER Input Output Expansion Module

The Mitsubishi Electric FX2N-32ER is a DIN-rail‑mountable digital I/O expansion module that adds 32 I/O points to MELSEC-F FX2N series PLCs (FX2N, FX1N, and FX3U) for control panels, conveyors, packaging equipment, and production lines. It provides 16 digital inputs and 16 relay outputs; inputs are digital DC 24 V with sink/source selectable, and outputs are relay-type rated up to about 2 A per point for resistive loads. The module is powered from 100–240 VAC, with opto‑isolated inputs and relay‑isolated outputs, and it mounts on a standard DIN rail. Its dimensions are approximately 90 mm wide by 87 mm deep, and it operates from 0 °C to 55 °C with IP20 protection. This expansion enables FX2N/FX1N/FX3U systems to increase I/O capacity, supporting retrofits, system expansions, and flexible machine control across automation environments such as conveyor systems, packaging machinery, automated assembly lines, process equipment, and material handling. Common replacements listed for this module include Mitsubishi FX3U-32ER/ES-A and FX5-32ER/ES, as well as Allen-Bradley 1769-OW16.
