1794-AENT FLEX I/O EtherNet/IP Adapter 8 Modules | Allen-Bradley

The Original New Allen-Bradley 1794-AENT FLEX I/O EtherNet/IP Adapter is a communication interface module that connects FLEX I/O modules to EtherNet/IP enabled controllers such as ControlLogix® or CompactLogix™. Featuring a single RJ45 Ethernet port with 10/100 Mbps communication rate, this adapter enables remote I/O control with advanced diagnostics and hot-swap capability. The adapter contains a built-in power supply that converts 24V DC to 5V DC necessary to transfer and receive all the I/O data and configuration for the entire rack.

Core Engineering Highlights:
8-module I/O capacity | 10/100 Mbps EtherNet/IP communication | Single RJ45 port | 24V DC nominal input (19.2–31.2V range) | 7.3W max power dissipation | 24.9 BTU/hr thermal dissipation | 450 mA @ 24V DC current load | -20°C to +55°C operating temperature | DIN rail mounting
