GT-3424 24 VDC Digital Input Gas Tube Protection Module
Overview
The GT-3424 provides gas tube protection for up to sixteen single ended inputs, as normally used with 24 VDC digital inputs.
The field inputs are terminated at 300 V barrier terminals, and further protected by a parallel combination of 90 V gas tubes, series inductance, and 31 V MOVs in parallel. The protected signal lines are then available for connection to low voltage electronic circuits via terminal blocks or mass termination connectors.
