The Omron NX-OD6121-6 Machine Automation Controller Digital Output Unit provides 32 NPN outputs for high-density industrial machine-control applications. The outputs support 12 to 24 VDC switching and use Switching Synchronous and Free-Run I/O refreshing for flexible control operation. With a response time of 0.1 ms ON and 0.8 ms OFF, the module supports applications requiring fast output switching across multiple connected devices. It operates from a 24 VDC supply across a 20.4 to 28.8 VDC range and has maximum power consumption of 5.80 W. The NX-OD6121-6 provides NPN transistor output control within the industrial PLC I/O range supporting Omron factory automation.
