Product details

The A-B 1756-CNBR ControlNet Bridge Module is an interface module manufactured by Allen-Bradley for communication within the ControlNet network. This module is redundant and provides higher network reliability and stability.

The following are detailed features of the A-B 1756-CNBR ControlNet Bridge Module:

Redundancy: The 1756-CNBR module has redundancy compared to the standard ControlNet bridge module. It has two ControlNet ports and supports both standard (simplex) and redundant ControlNet networks. This means that in the event of a failure of one port, the other port can take over the communication task, ensuring continuous operation of the system.

Interface and communication rate: The module has a Network Access Protocol (NAP) and is equipped with a shielded RJ-45 8-pin physical interface. It supports communication rates of up to 5Mbps, ensuring fast data transfer across the ControlNet network.

Number of logical connections: The A-B 1756-CNBR module supports 40-48 ControlNet logical connections, which means it can communicate with multiple ControlNet devices at the same time to implement complex control logic.

Power consumption: At 5.1 volts DC, the current consumption of this module is 1.0 amps. At 24 volts DC, its current consumption is only 2 mA, showing a low power consumption characteristic that helps reduce the overall energy consumption of the system.

ControlLogix Compatibility: As part of the ControlLogix family, the A-B 1756-CNBR module seamlessly integrates with ControlLogix's processors, I/O modules, and other components to ensure overall system stability and efficiency.

In practical applications, the A-B 1756-CNBR ControlNet Bridge Module is commonly used to connect the ControlLogix rack to the ControlNet network for high-speed, reliable data transfer and communication. It is especially suitable for industrial automation systems that require high reliability and redundancy functions, such as production line automation, process control and other fields.

Overall, the A-B 1756-CNBR ControlNet Bridge Module is A powerful and flexible industrial automation communication module with redundancy features to provide efficient and stable ControlNet network communication.
