Digital I/O module M500DMR

DIN rail mounted

The M500DMR provides supervision of two input circuits respectively from external switch devices and also provides two unmonitored single pole volt-free changeover contacts 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 Features Dual Input, Dual Output Module Input 2 (I2) and Relay 2 (R2) may be disabled individually using module DIP switches Uses 2, 3 or 4 module address spaces Common mechanical platform for box, panel and DIN rail mount versions Decade Address switches visible and selectable in two planes Wide angle LED visibility
