SNAP SI-160 SNAP Idle Relay Interface Module

SNAP SI-160 SNAP Idle Relay Interface Module is a SNAP bus interface device designed to provide a dedicated relay interface for idle-state signaling within Rockwell Automation's SNAP I/O ecosystem. The module plugs into a SNAP-compatible backplane and presents a discrete relay contact arrangement that can drive external signaling devices or interface with auxiliary control circuits, helping to separate field wiring from the PLC logic. Built for use with SNAP SNAP I/O configurations, the SI-160 integrates with other SNAP components in the same system, enabling straightforward wiring, diagnostics, and maintenance in automation cabinets. In typical applications where SNAP I/O is used—such as machine automation, packaging lines, conveyors, and processing equipment—the SI-160 serves as a compact, removable interface that simplifies interconnection between the controller and peripheral devices while providing reliable, isolated signaling for idle conditions. Its purpose-built design supports clean origination and termination of relay-based signals within a SNAP network, contributing to modular automation architecture and flexible rack/cabinet layouts.
