The Omron NX-OD6121 Machine Automation Controller Digital Output Unit combines 32 NPN transistor outputs for high-density machine-control applications requiring multiple output channels. It supports rated output control from 12 to 24 VDC and provides Switching Synchronous and Free-Run refreshing for integration with different machine sequences. Output response is 0.1 ms ON and 0.8 ms OFF, supporting fast switching of connected industrial devices. The module operates from a 24 VDC power supply with maximum power consumption of 5.80 W. The NX-OD6121 extends distributed output control within the NPN transistor PLC output range and supports scalable architectures using Omron industrial control systems.
