Analog Input Module

A general-purpose PowerLoop interface designed for third party detectors connected to the AutroSafe integrated fire and gas system and AutroSafe maritime gas detection system. The unit has a 4-20mA input galvanically isolated from the PowerLoop, and is a DIN rail version, bare PCB in an open DIN rail box, no DC/DC. The unit comprises the SelfVerify function. This function ensures the highest grade of reliability and reduces the need for manual testing, because all units comprising this function are automatically checked once every 24 hours.
