PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-ACNR15XT is a FLEX I/O ControlNet Adaptor module. It interfaces up to 8 FLEX I/O modules on a single communication node. The unit operates on an input voltage supply ranging from 19.2 to 31.2 Volts DC. It draws a nominal current of 400 milliamps during standard operation. Peak power dissipation reaches 3.4 Watts at an input level of 19.2 Volts DC.
This adapter module provides diagnostic indicators for its two communication ports and overall I/O status. ControlNet network connections require the recommended Belden RG-6/U coaxial cable. Power wiring terminals accept 22 to 12 AWG solid or stranded copper wire conductors. The device complies with North American T4A, ATEX T4, and IECEx T4 temperature codes. The physical unit measures 87.4 by 94 by 92 millimeters.
