PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-AENT is an Ethernet Adaptor within the FLEX I/O series. It enables industrial communication at rates of 10 or 100 Mbps. The unit links connected devices across an EtherNet/IP network. It supports an I/O capacity of up to eight modules. The built-in Flexbus connector enables communication with adjacent modules.
This adapter requires a nominal input voltage of 24V DC. Its operating input voltage spans from 19.2 to 31.2V DC. The device dissipates a maximum of 7.3W of power at 19.2V DC. Thermal dissipation reaches 24.9 BTU per hour at 19.2V DC. The open enclosure design supports DIN rail mounting with terminal screws torqued to 0.8 Nm.
