The 1761-NET-ENI is an Ethernet/IP communication interface manufactured by Allen Bradley/Rockwell Automation. It offers connectivity for the MicroLogix, CompactLogix and SLC 500 devices, and other DF1 full-duplex devices. It comes with a 100 Base-T Port, which is embedded with LEDs that allow for a reliable connection to the network through standard RJ45 Ethernet cable. These LEDs also offer easy-to-view links as well as transmit and receive statuses. The module also comes with an RS-232 communication port that provides isolation, and it auto-bauds upon power-up, thus detecting communications of the port setting of the respective controller attached to it. The 1761-NET-ENI Ethernet communication interface can force Ethernet to 11 Mbps or 100 Mbps as well as half or full-duplex. When configuring over Ethernet, a security mask provision can be used. Allen Bradley 1761-NET-ENI Ethernet/IP communication interface features a diagnostic page that helps to display essential module information as well as the Ethernet connections in use. Another advantage of this communication interface is that it’s efficient and offers outstanding output with less power consumption. Other specifications of the Allen Bradley 1761-NET-ENI communication interface include an operating temperature range of 0 – 70 degrees Celsius and a storage temperature of -45 to 85 degrees Celsius. It is also certified and listed for compliance with the IEC, UL, C-UL, CE, and Class 1, Division 2 standards. The unit has a non-condensing operating humidity of 5 – 95 percent, and it also allows for upload or download of programs. The 1761-NET-ENI module offers Ethernet/IP connectivity to the DF1 full-duplex devices, including CompactLogix and MicroLogix controllers.

The Allen Bradley 1761-NET-ENI Ethernet interface module requires a 24 volts direct current (DC) power source with a voltage range of 20.4 volts direct current (DC) to 26.4 volts direct current (DC). Additionally, this Ethernet interface module has a typical 24 volts direct current (DC) current draw of fifty (50) milliamperes. This product also has a maximum 24 volts direct current (DC) current draw of one hundred (100) milliamperes. The maximum inrush current of the Allen Bradley 1761-NET-ENI is two hundred (200) milliamperes. This Allen Bradley product also has an internal isolation rating of seven hundred and ten (710) volts direct current (DC) for a duration of one (1) minute. This Ethernet interface module can withstand an operating vibration rated at 5.0 G with a peak-to-peak displacement of 0.030 inches and a frequency ranging from 10 hertz to 500 hertz for a duration of 2 hours per axis. This Allen Bradley module can also withstand an operating shock rated up to 30 G. Additionally, it can withstand a non-operating shock rated up to 35 G when mounted via a DIN rail and 50 G when mounted via a panel mount. The Allen Bradley 1761-NET-ENI Ethernet interface module has an approximate weight of one (1) pound. Additionally, the physical dimensions of this module measure 118 millimeters x 52.07 millimeters x 64.8 millimeters, or 4.64 inches x 2.05 inches x 2.55 inches (height x width x depth). It is important to allow 15 millimeters, or 0.6 inches, of clearance for DIN latch movement during the installation and removal of this product.
