Trip Amplifiers

The range of Trip Amplifiers manufactured by Industrial Interface include loop powered trip amplifiers for 4-20mA signals and trip amplifiers with universal inputs and software configurable relay alarms. Input types include mA, Volts, thermocouples and RTD probes as well as slide wires and other potentiometers.

Some of the trip amplifiers are suitable for SIL1 and SIL2 safety applications and have been used throughout the process industries. The new 4002ALM-6 trip amplifier has a universal input stage, two programmable relay outputs and can be fully programmed through the 4 digit LED display on the front panel.

Please contact us if you can't see an immediate fit for your application as I'm sure we'll have a solution somewhere in our range.
