OMRON NX-OD3256 Transistor Output Unit for NX Series

The OMRON NX-OD3256 (NX-OD3256) is a compact digital output unit developed for distributed input and output expansion within the OMRON NX series. Designed for seamless integration with NX-series EtherCAT and EtherNet/IP couplers or compatible machine automation controllers, this transistor output module delivers reliable switching performance across high-speed industrial control architectures. It features four PNP transistor output points designed to operate at 24 VDC with a maximum load current rating of 0.5 A per point, providing efficient signal transmission to actuators, indicator lights, solenoids, and external switching devices. Engineered for high density and rapid signal processing, the NX-OD3256 ensures synchronous input and output operation when connected via EtherCAT networks, reducing machine cycle times in automated manufacturing environments. The modular slice design allows quick DIN rail mounting and simplifies system assembly, wiring, and unit replacement. This digital transistor output unit is commonly applied in packaging machinery, material handling systems, assembly automation, and food and beverage processing, where dependable DC load switching and precise timing control are essential for optimal machine operation.
