About 1794-OE8H
The Allen-Bradley 1794-OE8H output module is a Flex I/O 8-output HART analog output module. HART is an abbreviation for Highway Addressable Remote Transducer and it is an open standard protocol used to transmit and receive digital information over analog wiring. The 1794-OE8H output module is designed for use in the ControlNet and Ethernet networks and it provides 8 analog outputs which are non-isolated. The outputs can be configured to provide current in 2 configurable ranges which are 0 to 20 milliamps and 4 to 20 milliamps. The default output current range is 0 to 20 milliamps. Features available on the module include a remote transmitter alarm, overrange and underrange alarms, local microprocessor intelligence, and lead breakage detection. Module terminal bases which are compatible with the 1794-OE8H output module include the 1794-TB3G and 1794-TB3GS terminal bases.
The resolution supported by the 1794-OE8H output module is 13 bits. The absolute accuracy is 0.1% full scale at 68 degrees Fahrenheit. The module accuracy drifts 0.010% full scale for temperatures between 32 and 131 degrees Fahrenheit. The functional data range for the 1794-OE8H output module is greater than 15 Volts at 22 milliamps and it is greater than 22 Volts at 0 milliamps. The data format is configurable. The conversion type is the sigma-delta type. An external power supply with the catalog number 1794-PS13 is recommended for use with the module. This power supply is rated for 24 Volts DC nominal. The status indicators which are provided on the 1794-OE8H output module include 1 green power LED, 8 yellow HART LEDs, and 8 red fault LEDs. The maximum power dissipated by the 1794-OE8H output module is 6.1 Watts at 31.2 Volts DC. The module is available in an open enclosure.
The 1794-OE8H module is an output HART analog module. It belongs to Flex I/O family from Allen-Bradley.
