Omron CQM1-OC222 Open Collector Output Module

The Omron CQM1-OC222 Open Collector Output Module is an expansion card for Omron's CQM1 programmable logic controller that provides open-collector outputs to switch external loads from the PLC program. Open-collector outputs switch external loads by connecting through the transistor to a common reference when activated, making it straightforward to drive relays, lamps, or other DC devices from the controller. As part of the CQM1 family, the OC222 extends the controller's output capability, enabling scalable automation configurations in factory automation, machine control, and packaging lines. It adheres to Omron's wiring practices for open-collector interfaces, delivering reliable integration with the CQM1 I/O system for industrial environments.
