Single Channel Input Module

This is a single channel digital Input module. The Input Module is capable of receiving signals from 2, 3 or 4 wire devices and can provide a fused 24V dc output to power the field device if required. The unit includes protection from reverse voltage, surge/over voltage and RF interference.

This Input module is designed to interface with Industry standard Smoke detectors, Heat detectors, Manual Alarm Call Points, or any similar discrete device such as Flow switches, Push buttons, Pressure switches or Level switches. The module can support Intrinsically Safe circuit protection devices (both Zener Barriers and Galvanic Isolators).
