Banner Engineering SI-MAG1C Safety Interlock Relay Module

The Banner Engineering SI-MAG1C Safety Interlock Relay Module is a single-input, 24V AC/DC magnetic-gate monitoring module designed to interface Banner SI-MAG magnetic safety interlock switches with Banner safety controllers. Part of the SI-MAG family, this relay module provides the door/gate monitoring capability required for safe access to hazardous machinery and processes. It accepts a 24V AC/DC supply and features one input channel for monitoring a safety interlock, with its output signaling wired to the safety evaluation logic when the gate state changes. Banner lists the SI-MAG1C as a Magnetic Style Gate Monitoring Module and assigns it a part number of 46728; current product listings designate it as obsolete, reflecting its status as an older generation in the SI-MAG line. For proper safety integration, the SI-MAG1C is intended to be used with a Banner safety controller or the GM-FA-10J safety relay (or an approved equivalent) to form a complete safety function. Common applications include guarding doors and gates on industrial equipment, conveyors, and packaging lines where interlock monitoring is required to enforce safe stoppage and access control. This module delivers a compact, single-channel solution that pairs with Banner’s safety ecosystem to help meet functional safety requirements.
