The 1756-EN2T is a communication module from the 1756 ControlLogix product line by Allen-Bradley/Rockwell Automation. The module is a copper EtherNet/IP bridge supporting up to 256 Logix connections. Like other modules from the ControlLogix family, this module also has a communication rate of 10/100 megabits per second and a 30 Volts (continuous) isolation voltage. Furthermore, the isolation voltage has the basic insulation type, Ethernet to Backplane/USB to Backplane/USB to Ethernet connections, and it is type-tested at 980 Volts AC for 60 seconds. In addition, the 1756-EN2T communication module has a 1.0 Amp current draw at 5.1 Volts DC and a power dissipation of 6.2 Watts. Also, the 1756-EN2T model has a thermal dissipation of 17.4 BTU per hour. This communication module with a single slot width can be found as part of the chassis and it does not require a special slot place.

The 1756-EN2T module is designed for and works perfectly with ControlLogix chassis and both standard and redundant power supplies. Chassis models that can be used with this communication module are the 1756-A4/A7/A10/A13 and –A17. In addition, the module has 1 RJ45 Category 5 Ethernet port and a USB 1.1 port with full speed at 12 megabits per second. The module does not have a rated enclosure since it is an open-type device, and its operating temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). The storage temperature of the module ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit) and it operates in environments with a non-condensing relative humidity of 5 to 95%. Also, the 1756-EN2T communication module can withstand 2 grams at 10 to 500 Hertz vibration and 30 g of shock when operating. The module is certified according to various standards for controllers and similar industrial equipment. The included certifications include the c-UL-us, CE, CSA, RCM, FM, Ex, EAC, KC and EtherNet/IP standards.

The Allen-Bradley 1756-EN2T module is an Ethernet module that is made for communicating with other devices through the Ethernet network. The 1756-EN2T communication module is part of the Allen-Bradley ControlLogix series. It has a slot width rating of just 1 slot and it can be installed in any available slot in a ControlLogix chassis. Its power dissipation rating is 6.2 Watts per hour and its thermal dissipation rating is 21.28 BTU per hour. The 1756-EN2T communication module can communicate over the Ethernet/IP network at speeds of 10 to 100 Mbps. The integrated communication ports that are found on this module include the USB 1.1 port and the RJ45 port. The users can configure the 1756-EN2T communication module with either the RSLogix 5000 software or the Studio 5000 Logix Designer software.


The Allen-Bradley 1756-EN2T Ethernet communication module operates in a temperature range from 32 to 140 degrees Fahrenheit or 0 to 60 degrees Celsius. It is well suited to motion control, time synchronization, and real-time control applications. This communication module can handle as many as 128 TCP/IP connections and as many as 256 Logix connections at a time. The 1756-EN2T communication module can also connect to SCADA devices, a programming workstation, an HMI or Human-Machine Interface, and several kinds of 3rd-party devices all at the same time. It is designed to support a linear network topology. The 1756-EN2T communication module can communicate through the DeviceNet network and the ControlNet network as well as through the Ethernet/IP network, which is an open protocol that allows for a high degree of flexibility.

The 1756-EN2T Ethernet module from Allen-Bradley can communicate through the Ethernet/IP, DeviceNet, and ControlNet network protocols. It is part of the Allen-Bradley ControlLogix series.
