1756-CNBR Allen Bradley ControlLogix Communication Module Isolation Voltage 30 Volts Continuous

1756-CNBR Allen Bradley ControlLogix Communication Module

The Allen-Bradley 1756-CNBR is a ControlNet Bridge Module. This module is part of the ControlLogix product family that is used to interface a ControlLogix controller or implement Distributed I/O architecture via the high-speed ControlNet network. This module features Two (2) ControlNet ports, enabling connection to standard (simplex) and redundant ControlNet networks.

Like the non-redundant module, the 1756-CNBR also controls scheduled data in conjunction to the Logix5550 Controller and bridges unscheduled data between the ControlLogix backplane and the ControlNet Network.

The technical specifications of this module are also similar to the non-redundant module. It can also handle up to 64 bidirectional scheduled and unscheduled connections with other ControlNet devices. Aside from that, up to 20 buffers for unconnected messages can be supported by the module. Also, this is the module needed if your application has 40 to 48 Logix communication connections per communication module and the communication rate is 5 megabytes per second. It also has 99 nodes available.

The current draw for the 1756-CNBR is 970 milliamperes at 5.1 Volts DC and 1.7 milliamperes at 24 Volts DC.

The 1756-CNBR supports transmission rate of 5Mbps, which is the standard transmission rate of the ControlNet protocol. It uses a quad shield RG-6 coaxial cable as trunk cable and established connection to the trunk cable with the use of ControlNet taps. This module supports 40-48 Logical communication connections and a maximum of 64 connections. The maximum number of nodes supported by the 1756-CNBR is 99 nodes.
