The electrical alarm unit GAE953 gives a signal when one or two set alarm values have been exceeded. Input signals from 0/4 to 20 mA, from 0 to 10 V, from 1 to 5 V, from 0/0.2 to 1 V can be processed as input variables. The device has two inputs with min. (= low) or max. (= high) monitoring, but they can also be switched together for min. and max. monitoring of a single input or of a difference between 2 inputs. The digital display at the front plate permits the control of the inputs as well as the set alarm values.
