The Omron CP1W-20EDR1 PLC Expansion I/O Unit adds digital I/O capacity to compatible Programmable Logic Controller systems used for machine and process control. Its output section provides 8 relay outputs, allowing controller logic to switch compatible field devices through relay contacts. The module consumes 103 mA at 5 V and 44 mA at 24 V, supporting integration into compact control architectures where additional I/O points are required. It can be used when an existing PLC needs more field connections without changing the primary controller platform. The CP1W-20EDR1 belongs to the CP1W expansion architecture and forms part of the relay output PLC expansion range developed for Omron machine automation.
