Allen-Bradley 1768-CNB | CompactLogix ControlNet Communication Module

Product Overview

The Allen-Bradley 1768-CNB is a CompactLogix ControlNet communication module designed for industrial automation systems. It provides reliable networking capabilities, supporting up to 48 simultaneous connections and a maximum of 99 nodes. With a ControlNet data rate of 5 Mbps, the 1768-CNB ensures efficient and low-latency communication across your control network.

This module occupies a single slot on the CompactLogix chassis and draws 1 ampere from the backplane at 5 volts. Its robust construction supports mounting via DIN rail or panel installation, making it versatile for various industrial setups.

Engineered for industrial environments, the 1768-CNB operates between 0°C and 60°C, withstanding vibrations up to 5 g and shocks up to 30 g. Non-operating conditions allow -40°C to 85°C and shocks up to 50 g, ensuring durability and longevity.

The module includes one BNC connector for non-redundant media and one NAP (RJ45, 8-pin shielded) connector, allowing flexible network configurations. Its compact size and lightweight construction of 0.63 lbs (0.28 kg) simplify integration into existing automation systems.
