About 1794-ADN

The Allen-Bradley 1794-ADN is a 24 Volts DC DeviceNet media adapter module. It can support up to 8 I/O modules and it has communication rates of 125 Kbps, 250 Kbps, and 500 Kbps. The status indicators in the 1794-ADN allow the users to monitor the I/O and ModNet status. The module has an open-type enclosure and it can mount on a DIN rail or a panel. It also comes with 1 DeviceNet port that uses an open 5-pin or 10-pin linear plug. The entire 1794-ADN module measures 3.7 x 3.6 x 3.4 inches. Its power ports use Category 1 wire, while the communication ports use Category 2 wire. This adapter module has a power supply current load of 400 mA at 24 Volts, while its DeviceNet power rating is 24 Volts DC at 90 mA. Note that a power supply of 24 Volts DC needs to be able to supply an inrush surge current of 14 Amps for 5 milliseconds to each adapter that is connected to the power supply. It has a nominal input voltage of 24 Volts DC and a maximum FlexBus output current of 640 mA at 5 Volts DC. Its input voltage range is from 19.2 to 31.2 Volts DC and this includes the 5% AC ripple.

The 1794-AND module also has a maximum current draw of 400 mA at 24 Volts DC. The DeviceNet module has its own power requirement with a maximum power requirement of 24 Volts DC (+/- 4%) voltage at 90 mA. The 1794-ADN has been type-tested at 1,930 Volts DC for 60 seconds, and it has a continuous isolation voltage of 50 Volts. Its maximum power dissipation is 7.6 W at 19.2 Volts DC and its thermal dissipation is 26 BTU/hour at 19.2 Volts DC. Its operating temperature range is -4 to 158 degrees Fahrenheit while its storage temperature range is -40 to 185 degrees Fahrenheit. The 1794-ADN comes with a vibration rating of 5 g at 10 to 500 Hertz, an operating shock rating of 30 g, and a non-operating shock rating of 50 g.
