Allen-Bradley 1756-CN2 Communications Bridge Module is a single-slot, Series C ControlNet bridge for ControlLogix systems that links a ControlNet network to the controller backplane, enabling deterministic data exchange with remote I/O. It supports up to 99 nodes and 131 connections on the ControlNet network and operates at a 5 Mbps data rate. Powered from the backplane, it draws 1.1 A at 5.1 V DC and occupies one chassis slot, weighing about 0.57 lb; the bundle includes a cable. Typical applications include bridging remote ControlNet I/O racks with a ControlLogix controller for centralized control and data collection.
