The Allen-Bradley 1771-OZC is a digital relay contact output module featuring eight normally-open output points, ideal for applications requiring careful switching capabilities. It operates within a 0-24V DC range and handles a maximum continuous current of 0.1 A per module, with voltage limits of 30 VA at 138V AC and 20 VA at 125V DC. Designed for efficiency and compact installation, it provides precise AC and DC signal control with typical delays of 45 ms and 50 ms, respectively, when off, making it suitable for rack mounting with a 1771-WD wiring arm.
