The 1761-NET-ENI has a 100 Base-T Port embedded with LEDs which allow for reliable connection to your network through any standard RJ45 Ethernet cable. These embedded LEDs provide easy-to-view links and transmit/receive statuses. It is equipped with an RS-232 port which provides isolation and will auto-baud on power-up for detecting the communications of the port setting of the controller attached to it. The 1761-NET-ENI is provided with the ability to force Ethernet to 11 Mbps or 100 Mbps and half-duplex or full-duplex where the default us auto negotiable. Configuration over Ethernet can be done with a configuration security mask provision.

Its most vital feature is the diagnostic page which displays the important module information and all the Ethernet connections in use. One of the best things about the 1761-NET-ENI communication interface is that it is efficient and delivers exceptional output with less power consumption. The maximum operating temperature for the 1761-NET-ENI is 0 to 70 degrees Celsius and the maximum storage temperature is -45 to 85 degrees Celsius. The most commonly used standards are IEC801-2, 3, 4, 5, and 6. Its operating humidity is 5-95% non-condensing. The 1761-NET-ENI’s regulation, approvals, and certifications include the UL, C-UL, CE, and Class 1, Division 2 certifications; this module provides Ethernet/IP connectivity to all DF1 full-duplex devices including all MicroLogix and CompactLogix controllers. This Ethernet Interface allows you to upload or download programs, communicated between controllers and generate emails while connected to non-Ethernet controllers.
