Allen-Bradley 1756-CNB ControlNet Bridge Module

This is an Allen-Bradley ControlLogix ControlNet bridge module. It's designed for industrial automation setups where you need to link a ControlLogix chassis to a ControlNet network. It has the standard RJ45 port on the front and the status display at the top. Used, but it's in decent physical shape with some typical wear from being in a rack. It's a solid piece of hardware if you're maintaining or expanding an older PLC system.
