The Allen-Bradley 1768-CNB is a CompactLogix communication module designed for reliable and high-speed data transfer over the ControlNet network. Manufactured by Rockwell Automation, this module supports a wide range of applications including media redundancy, intrinsic safety, and redundant controller system configurations. The 1768-CNB is built to handle demanding industrial environments, with an operational shock tolerance of 30 g and a non-operational shock limit of 50 g. It operates within a temperature range of 0°C to 60°C (32°F to 140°F) and can be safely stored between -40°C and 85°C (-40°F to 185°F). The module ensures deterministic and repeatable data delivery, making it ideal for high-performance control and communication tasks.
