CJ1W-OD261 Omron Transistor Output Unit 64 Points NPN 0.3A 12-24VDC High-Speed CJ Series PLC Module

CJ1W-OD261 Product Overview

The CJ1W-OD261 is a high-performance transistor output unit from Omron's CJ Series PLCs, featuring 64 digital output points with NPN transistor (sinking) outputs, each rated at 0.3A (0.5A momentary). The CJ1W-OD261 supports a wide 12-24V DC output voltage range (permitted 10.2-26.4V DC). It uses two FCN40-type 40-pin rectangular connectors for external wiring, with a compact width of only 31mm and a weight of approximately 110g. As a Basic I/O Unit in the CJ Series, the CJ1W-OD261 features short-circuit protection and supports high-speed output. It is widely used in industrial automation control systems to drive relays, solenoids, indicator lights, and other external loads. Certified to CE, cULus, Lloyd's, NK, and other international standards.
