About 1794-ACNR15

The 1794-ACNR15 Flex I/O ControlNet adapter module by Allen-Bradley is part of a programmable controller system. It is capable of high-speed data transfer, diagnostic messages, and local communication via a network access port on the ControlNet network. The 1794-ACNR15 can support 8 I/O modules connected via a quad shield RG-6 coaxial cable with a communication speed of 5 Mbps. It has an input voltage rating between 19.2 and 31.2 Volts DC (24 Volts DC nominal) at 400 mA and an output voltage rating of 5 Volts DC at 640 mA. It has an inrush current of 23 Amps through 2 milliseconds and draws a maximum 450mA current at 24 Volts.

The 1794-ACNR15 has an indicator which shows the I/O mode and status. It has a maximum flexbus output current of 640mA and an isolation voltage of 850 Volts tested for 1 second between power and the flexbus. The 1794-ACNR15 can be mounted using a DIN rail or wall mount via 7 pound-inches terminal screws. Its dimensions of 87 x 94 x 69 millimeters and it weighs approximately 220 g (7.76oz). The 1794-ACNR15 has a T4 temperature code and dissipates 3.4 W of heat at 19.2 Volts DC in an open-style enclosure type rating. It has an operational temperature range between -25 and 55 degrees Celius (-13 and 131 degrees Fahrenheit) at 5-95% non-condensing relative humidity. It has a maximum operational shock rate of 30G and can reach 50G in non-operational mode and a 5.0G operational vibration at 10 to 500 Hertz.
