1794-ACNR15  Allen-Bradley   Flex I/O communication adapter

This module requires an external power supply to function. Acceptable supply voltage range is 19.2…31.2V DC, with current of 400 mA. The nominal supply voltage is 24VDC. For power connections, use 0.33… 2.5 sq. mm (22…12 AWG) solid or stranded copper wire with insulation rating of 75 °C (167 °F) or greater and maximum insulation thickness of 1.2 mm (3/ 64 in.). For Double wire connection, use 0.33… 1.3 sq. mm (22…16 AWG) solid or stranded copper wire that are not intermixed, with insulation rating of 75 °C (167 °F) or greater and insulation thickness of 1.2 mm (3/64 in.).

The 1794-ACNR15 has LED indicators that provide operational status of the module. These LED indicators include I/O status, Comm A for ControlNet port A status and Comm B for ControlNet port B status. These LED status indicators are useful monitoring and troubleshooting aids which convey specific message.

The 1794-ACNR15 can be mounted using a DIN rail or wall mount with Torque requirement of 7 pound-inches. The module’s dimensions are 87x 94x 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 Celsius (-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.
