NX-OD5256 16-Point PNP Digital Output Module 0.5A 12mm | Omron

The Original New Omron NX-OD5256 16-Point PNP Digital Output Module is a high-density transistor output unit for the NX series I/O system. Designed for machine automation and factory control applications, it provides 16 PNP (sourcing) outputs rated at 0.5 A per point with short-circuit protection. The screwless push-in terminal block enables tool‑free wiring for fast installation and maintenance. Part of the NX series for EtherCAT communication coupler systems.
