Allen-Bradley 1756-OX8I is a ControlLogix eight-point isolated relay output module that provides eight relay contacts in a single 36-pin block. Each output is isolated from the backplane, enabling discrete switching of loads within a ControlLogix I/O chassis. This module is designed for industrial automation tasks where eight relays are needed to control field devices or indicators from the controller, and it is part of the 1756 ControlLogix I/O family. Firmware for the 1756-OX8I is listed as v3.003 on the official product page.
