Allen-Bradley 1771-OZL

The 1771-OZL module has 8 Form A relays. The outputs are arranged in 4 groups of 2, each group with its own common. Each output is electrically isolated from module logic circuitry. The module can simultaneously switch all 8 outputs to separate loads, each conducting a maximum load of 100mA continuously, at rated power. Ac loads switched by the modules should have a power factor (PF) of 1.0.

This module does not contain surge limiting circuitry. Use this module for switching resistive loads only. It is not recommended for inductive or capacitive loads.

Use the plastic keying bands, shipped with each I/O chassis, to key your I/O slots to accept only this type of module. Place the keying bands on the chassis backplane between: 6 and 8, 16 and 18. Slots on the rear edge of the circuit board are matched to these slots to allow insertion of this type of module. You can key any connector in an I/O chassis to receive this module except for the leftmost connector reserved for adapter or processor modules.
