Function: Single Level Latching Trip Amplifier from a single process signal input. Two separate set points allow for setting of the trip set point at which point the relay will be latched and the release set point at which the relay will be unlatched. The AL Block can be manufactured with either a Low Trip set point or a High Trip set point. In both cases as the signal passes Down (for a Low Trip) or Up (for a High Trip) through the trip set point the relay will be energised and will remain energised until the signal passes back through the release set point when it will be de-energised. The AL Block is ideally suited to maintaining levels in a tank between two pre-set levels either for filling using the Low Trip version or for emptying using the High Trip version.
