The Allen-Bradley 1746-OW4 is a versatile relay contact output module featuring four relay outputs designed for various AC/DC applications. Operating within voltage ranges of 5-125V DC and 5-265V AC, this module supports a signal delay of 10 ms for both ON and OFF states. It consumes a backplane current of 0.045A and provides a maximum thermal dissipation of 1.9 W. With a focus on precise performance, it maintains a minimum load current of 1 mA at 5V DC and a maximum continuous current of 8A per module, making it essential to periodically inspect the module for degradation due to chemical exposure, to maintain its reliability.
