PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-ACNR15 is a FLEX I/O ControlNet Adaptor for distributed industrial systems. It enables communication between a ControlNet network and connected I/O hardware. The unit supports up to eight FLEX I/O modules on a single backplane. Two BNC connectors designated as A and B provide connections for ControlNet network cables. A built-in Network Access Port provides connection access for programming terminals.
This adaptor operates across an input voltage range of 19.2 to 31.2V DC. It draws an input current of 400 mA during standard operation. The device supplies a regulated 5V DC output with 640 mA capacity to connected modules. It handles an inrush current of 14 Amps for 2 milliseconds during startup. Operating temperatures for the unit range from -13 to 131 degrees Fahrenheit. The module has a maximum power dissipation of 3.4 Watts at 19.2V DC.
