20-ALM Loop Powered Trip Amplifier
£100.77
The 20-ALM is a unique loop-powered trip amplifier which can be wired into any 4-20mA loop and provide a single N.O or N.C alarm relay output.
The setpoint is set using a front panel potentiometer and can be checked by measuring a 0-1V signal on the setpoint terminals. Two relay types are available, one suitable for DC voltage switching and the other for switching higher AC voltages.
