The Omron CP1W-16ET PLC Digital Output Expansion Unit provides 16 sinking transistor outputs for adding electronic switching capacity to compatible Programmable Logic Controller systems. These outputs allow PLC logic to control additional compatible DC field devices when the existing controller does not provide enough output points for the machine configuration. The module consumes 76 mA at 5 V and integrates into the CP1W expansion architecture, allowing digital output capacity to grow while retaining the existing PLC platform. Its 16-point configuration suits machines requiring a moderate number of additional transistor-controlled outputs. The CP1W-16ET extends CP1W output capability and belongs to the 16-point sinking PLC output range available for Omron industrial automation.
