Omron CPM1A-20EDT1 Digital I/O Expansion Module

The Omron CPM1A-20EDT1 digital I/O expansion module adds 20 I/O points to Omron CPM1A PLC systems, delivering 12 digital inputs and 8 transistor (NPN) outputs to extend control for sensors, actuators, relays, and field devices in industrial automation. It uses 24 VDC inputs and is powered via the PLC's 24 VDC supply, with screw-terminal connections for reliable DIN rail mounting and built-in I/O isolation for electrical noise resistance; LED indicators provide at-a-glance status. The module is designed for 0°C to +55°C operation and is compatible with the CPM1A series, making it suitable for control panels, packaging machines, conveyors, and other small automation equipment requiring scalable I/O points. Common replacements in the Omron CPM1A ecosystem include CPM1A-20EDR1 and CP1W-20EDT, underscoring its role within a modular, scalable automation solution.
