OMRON NXSIH400 4-Channel Safety Input Module for NX Series

The OMRON NXSIH400 (NXSIH400) is a four-channel safety input module developed for use within Omron NX series control architectures. Built to deliver functional safety compliance in automated machinery, this modular unit is certified for applications requiring Safety Integrity Level 3 (SIL3) and Performance Level e (PLe) standards. It functions within programmable logic controller setups to monitor safety circuits and verify input status across safety-critical industrial applications. Designed for the NX series platform, the NXSIH400 provides four safety input channels that interface with safety field devices to ensure responsive and dependable machine monitoring. The module operates in conjunction with compatible NX series bus systems, facilitating centralized or distributed machine safety integration. Typical applications include manufacturing assembly lines, robotic cells, packaging equipment, and automated production machinery where SIL3 and PLe functional safety monitoring is required to protect personnel and equipment.
