The Omron NX-OD3257 Machine Automation Controller Digital Output Unit combines 4 PNP transistor outputs for high-speed 24 VDC machine-control applications. It supports Switching Synchronous and Free-Run refreshing for flexible output processing within industrial control sequences. A 300 ns ON/OFF response enables rapid switching where precise output timing is required. The unit operates from a 24 VDC power supply with maximum power consumption of 5.80 W, supporting integration into compact modular automation systems. The NX-OD3257 combines high-speed PNP transistor switching with NX modular architecture and belongs to the high-speed PLC output range supporting Omron factory automation.
