NX-OD5121 16-Point NPN Digital Output Module 0.5A 12mm | Omron

The Original New Omron NX-OD5121 is a 16‑point NPN (sinking) transistor output module for the NX series I/O system. Designed for general‑purpose output expansion, it provides 16 solid‑state outputs rated at 0.5 A per point. The module features a 12 mm width, a screwless push‑in terminal block for tool‑free wiring, and short‑circuit protection. Part of the NX series for EtherCAT and EtherNet/IP communication coupler systems, it supports both free‑run and synchronous I/O refreshing.
