Analog Input Module

The System Sensor M500M-4-20 analog input module demonstrates our commitment to offer solutions for all applications.

Overview

Analog Input Modules includes numerous safeguards and protective features to ensure trouble-free operation. The modules accepts both 3-wire (device sink) and 2-wire configurations. The external power supply is isolated from the communication line. In addition, a 500 mA current limiter and a cut off circuit protect the module’s electrical supply from short circuits. In the event of a short, the output voltage will cycle within safe limits until the short is removed. The output signal is sampled and filtered for transients and noise prior to passing the signal on to the FACP. If the current running through the sensing circuitry exceeds 25 mA, the output voltage will shut down and the short protection process will begin.
