M221E

Dual Input Single Output Module

m221e

The M221E provides supervision of two input circuits from external devices and an unmonitored single pole volt-free changeover contact for external devices. The module features a built-in short-circuit isolator. 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.

  • Common mechanical platform for box, panel and DIN Rail mount versions
  • Tri-colour LEDs with wide-angle LED visibility
