The Omron NX-OD5256-1 Machine Automation Controller Digital Output Unit provides 16 PNP transistor outputs for industrial machine-control applications requiring 24 VDC output switching. It supports Switching Synchronous and Free-Run refreshing, enabling the module to operate within different control and distributed I/O configurations. The unit provides a response time of 0.5 ms ON and 1.0 ms OFF for consistent command execution. It operates from a 24 VDC power supply with maximum unit consumption of 5.80 W. The NX-OD5256-1 combines PNP transistor switching with modular NX architecture and belongs to the PNP output PLC I/O range used across Omron machine control.
