Quadruple level trip amplifiers operate from a single process input with a quadruple trip action which can be arranged so that the alarm conditions are triggered either above or below the defined set points. (High Trip or Low Trip). The relays 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 two models of quadruple level trip amplifier.
