RFQ to Check

Description: 1761-NET-ENI is an Ethernet Interface for MicroLogix and CompactLogix devices by Allen-Bradley with DF1 Full-Duplex Protocol, RS-232 ports, and a DC Input Power. Uses RS-232 Ports. 50 Milliampere Current Draw at 24V DC. DF1 Full-Duplex Protocol.

1 year Warranty Included



The Allen-Bradley 1761-NET-ENI is an Ethernet/IP communication interface. It provides connectivity for CompactLogix, MicroLogix, and SLC 500 devices, as well as other DF1 full-duplex devices. 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.

The 1761-NET-ENI’s 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.
