Description
Sinamics NX-OD4121 Overview

The NX-OD4121 is a compact 8‑point NPN transistor output module for the Omron NX I/O system, designed for high‑speed, stable machine control. It supports both synchronous and free‑run I/O refreshing, ensuring precise timing matching with controller cycles. With a space‑saving 12mm width, detachable push‑in terminals, and built‑in short‑circuit protection, it simplifies wiring, maintenance, and system integration. Operating at 12–24VDC with 0.5A per output, it is widely used in factory automation, assembly lines, and motion control systems for reliable digital signal output.
