Product Overview
The Omron CJ1W-OD212 is a 16-point transistor output module for CJ1 series PLCs, featuring high-current outputs rated at 2A per point for driving larger DC loads directly without interposing relays. This module features NPN (sinking) transistor outputs operating at 12-24VDC, suitable for solenoid valves, small contactors, motor starters, and other DC loads requiring higher current capacity than standard output modules provide. The 2A per point rating makes the CJ1W-OD212 ideal for applications where direct drive capability reduces system complexity and cost by eliminating external relay banks. The module includes individual LED status indicators for each output point, enabling quick visual verification of output states during commissioning and troubleshooting. Built-in protection features include short circuit protection and overload protection, safeguarding both the module and connected field devices from damage due to wiring faults or overload conditions. The module connects to field wiring through a standard 40-pin connector, providing secure and organized connections. With fast response times of 0.5ms or less, the CJ1W-OD212 is suitable for high-speed control applications where timing precision is important. The module mounts directly to the CJ1 backplane, drawing logic power from the PLC power supply while field power is connected through the external connector. Applications include hydraulic and pneumatic valve control, motor starter control, high-power indicator systems, and any application requiring direct drive of higher-current DC loads from the PLC.
