The System Sensor Analogue Addressable Dual Input Single Output Module M221E supervises two input circuits from external devices and also provides an unmonitored single pole volt-free changeover contact for external devices. Input channels are capable of both latched and analogue supervision there are three separate latched states Normal, Open-Circuit and Combined Alarm/Short. The analogue supervision continuously monitors the supervised circuit, returning a signal proportional to the circuit resistance.
