PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-AENTR is an Ethernet Adaptor designed for the FLEX I/O modular system. This dual-port communication unit interfaces an EtherNet/IP network with up to eight connected FLEX I/O modules. Communication rates support both 10 Mbps and 100 Mbps operation over Category 5 media.
Electrical operation requires a nominal 24V DC power input with a range of 19.2V to 31.2V DC. The unit withstands inrush currents reaching 18 Amps for up to 2 milliseconds. Integrated status indicators provide immediate visual feedback regarding network connectivity and hardware operation. Continuous isolation voltage is rated at 50 Volts to help prevent electrical fault damage.
