  • LED indication of Alarm
  • Unique Low cost solution

The 20-ALM is a 4-20mA direct current loop powered trip amplifier. The device derives its power from the input signal and therefore requires no external power supply.

The output of the 20-ALM is a single pole, normally open, solid state relay which can be configured to close either above or below the adjustable setpoint. The switched output can be connected to any potential within 1kV of the transmitter supply, while transients of 2.5kV can be withstood.

The relay is designed to switch AC or DC.
