Single level trip amplifiers operate from a single process input, with a single trip action which can be arranged so that the alarm condition is triggered either above or below the defined set point. (High Trip or Low Trip). The relay can also be configured for a Fail Safe, (energised in the stable state to de-energise in the alarm state) or Non-Fail Safe (de-energised in the stable state to energise in the alarm state) operation.
We supply five models of single level trip amplifier including SIL rated versions.
