Allen-Bradley 1797-OE8H

The Allen-Bradley 1797-OE8H FLEX Ex HART I/O Module has 8 Outputs and a Single-ended Non-isolated Output Type. It operates with a 15V @ 22mA Load Range Voltage and a 13 bits Resolution.

The 1797-OE8H module is an output module from the Flex Ex I/O series of modules. It has been designed and manufactured by Allen-Bradley/Rockwell Automation. The 1797-OE8H output module comes with 8 outputs. It is meant to be mounted on a DIN rail and it can be grounded through the DIN rail. However, this is only possible if the DIN rail is made of zinc-plated yellow chromate steel. All of the outputs on the 1797-OE8H output module are single-ended and they are not isolated from each other. This output module supports RIUP or Removal and Insertion Under Power, but this should only be done in areas that are non-hazardous and even with this feature, it is still recommended to disconnect the backplane power and all connected input and output devices before removing the 1797-OE8H output module.

The Allen-Bradley/Rockwell Automation Flex Ex I/O series 1797-OE8H output module consumes about 6.1 Watts of field side power. Its power dissipation rating is 5.4 Watts while its thermal dissipation rating is 20.8 BTU per hour. Its load range current ratings are 0 to 22 milliamps and its load range voltage rating is 15 Volts at 22 milliamps. The 1797-OE8H output module weighs about 200 grams. Its operating temperature range is -20 to 70 degrees Celsius or -4 to 158 degrees Fahrenheit and its storage temperature range is -40 to 85 degrees Celsius or -40 to 185 degrees Fahrenheit. The 1797-OE8H 8-channel output module can tolerate 5 to 95% relative humidity in operation and storage as long as there is no condensation.
