CJ1W-OD211 Product Description Omron CJ1W-OD211, also named CJ series 16-point NPN transistor digital output unit, is an I/O expansion module for CJ1 series PLC system. It is designed to convert internal PLC logic signals into DC switching signals to drive solenoid valves, relays and indicators, supporting digital output control for automation equipment renovation.

This module delivers reliable output driving for machine control tasks. The output driving supports DC12~24V load power supply with 0.5A per point rated current. The output driving realizes high-speed ON/OFF switching of 16 independent output channels. Stable output driving completes actuator triggering according to PLC program instructions.

The built-in transistor circuit achieves steady signal conversion. The signal conversion receives command data from CJ backplane bus and outputs sink type switching signal. The signal conversion features fast response time and low residual voltage. Accurate signal conversion ensures field actuators respond synchronously with control logic.

Backplane plug-in structure brings convenient system assembly. System assembly can be inserted directly into CJ series PLC rack. System assembly connects field loads via removable screw terminal block. Flexible system assembly is widely used for legacy CJ1 system spare replacement.

CJ1W-OD211 supports short-circuit protection and module status diagnosis function, equipped with removable terminal block for field wiring. It has LED indicators for channel status and module fault diagnosis. Widely applied in packaging machines, conveyor systems and automated processing equipment. This product is available as industrial spare parts, complying with Omron CJ series PLC I/O module standards.
