PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-OZC PLC-5 Contact Output Module provides eight normally open digital relay contact outputs. It operates within a direct-current voltage range of 0 to 24V DC. Chassis backplane current draw for the module is 420 mA. The maximum continuous current rating per module is 0.1 A. The unit installs directly into a standard 1771 I/O chassis.
Output circuits support maximum ratings of 30 VA at 138V AC or 20 VA at 125V DC. Switch turn-off response features a typical AC signal delay of 45 ms. The typical DC turn-off delay is 50 ms. Field wiring connects via a 1771-WD or 1771-WH wiring arm. The module contains mercury in a glass capsule and requires careful handling.
