The 1756-ENBT is an Ethernet/IP communication module that belongs to the 1756 series of ControlLogix Communication Modules. This module has been designed by Allen-Bradley and it works as a bridge between two or more devices like, for example, a controller and an I/O module. The Allen-Bradley 1756-ENBT Ethernet/IP communication module operates with a network protocol that is an open industrial networking standard nowadays, this protocol supports real-time I/O messages and data exchange. This module allows users to connect control I/O and drives and communicate with other Ethernet/IP devices, acting as a bridge to send messages to devices on other networks and as an adapter for I/O on remote links.

The Allen-Bradley 1756-ENBT Ethernet/IP communication module has a current draw of 700 mA at a voltage of 5.1 Volts DC and 3 mA at 24 Volts DC. It has a power dissipation of 3.7 Watts, a thermal dissipation of 12.6 BTU per hour, and an isolation voltage of 30 Volts. This module has one Ethernet RJ45 Category 5 port and it does not have USB ports. The Ethernet cables can be shielded or unshielded. The Allen-Bradley 1756-ENBT Ethernet/IP communication module features 64 TCP connections and 128 CIP connections. These CIP connections can be used for any combination of connections on implicit applications. The recommended conditions are a relative humidity of 5 to 95% and an operating temperature of 0 to 60 degrees Celsius. This module does not have any kind of enclosure and it can be located In any slot. Due to the nature of the module, it should not be exposed to temperatures higher than the recommended range.

The 1756-ENBT ControlLogix bridge module is an Ethernet/IP bridge by Allen-Bradley. It provides an Ethernet speed of 10 to 100 Mbps. This communication module is used to transfer data and information by using the Ethernet port. The bridge is capable of handling high-speed communication and it comes with auto-negotiating functions. It supports real-time I/O messaging, information exchange, and general messaging. It meets the common industry protocol (CIP) for safety in data transmission. The 1756-ENBT bridge has a current draw of 700 milliamps at 5.1 Volts DC. The power dissipation of the bridge module is 3.7 Watts and it has a thermal dissipation rating of 12.6 BTU/hour. Basic insulation is present with an isolation voltage of 30 Volts from the Ethernet network to the backplane. It has a slot width of 1. 


The Allen-Bradley 1756-ENBT ControlLogix Ethernet/IP bridge module can be installed in any slot of the chassis. The ambient temperature should be set between 0 and 60 degrees Celsius for normal operation. A single Ethernet RJ 45 Cat 5 port is present on the front of the module. Both shielded and unshielded twisted pair cables are supported for communication. No USB port is available in this bridge module variant. The 1756-ENBT bridge module supports upto 128 Logix connections. It has a current rating of 3 milliamps and voltage rating of 24 Volts DC. The bridge is able to process up to 5000 I/O packets per second at a time. The 1756-ENBT bridge module can be easily configured using the RSLogix 5000 programming software by connecting it with a personal computer or a programming terminal.

The 1756-ENBT bridge module is an Ethernet/IP bridge by Allen-bradley. It has a voltage rating of 24 Volts DC.
