The Omron CP1W-8ET PLC Digital Output Expansion Unit provides 8 sinking transistor outputs for adding electronic switching capacity to compatible Programmable Logic Controller systems. These transistor outputs allow PLC control logic to operate additional compatible DC field devices when more output points are required beyond those available on the primary controller. The module consumes 75 mA at 5 V and integrates with the CP1W expansion architecture as part of a compact machine-control configuration. Its eight-output design is suited to applications requiring a limited number of additional transistor-controlled switching points. The CP1W-8ET extends CP1W digital output capability and forms part of the 8-point sinking PLC output range within Omron machine control systems.
