PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-AENTRXT is a FLEX I/O dual-port Ethernet Adaptor. It delivers network communication for distributed industrial systems. The unit supports up to eight I/O modules on a backplane. It provides two Ethernet Category 5 connectors supporting 10/100 Mbps data rates. Status indicators display conditions for module status, network status, Link 1, and Link 2.
This adapter operates on a nominal 24V DC power source. The acceptable input voltage spans from 19.2 to 31.2V DC. Typical current draw is 400 mA at 24V DC with 500 mA peak current. The module has an open enclosure design with conformal coating. This coating meets ISA / ANSI-71.040 1985 noxious gas standards. Technicians must mount the module on a grounded DIN rail.
