1794-OE4 AB
About 1794-OE4
The 1794-OE4 industrial module is an output module. It is part of the Allen Bradley Flex I/O product line, which also includes input modules and combination modules. The 1794-OE4 output module provides four non isolated single ended outputs. The resolution supported by the module is a 12 bit plus sign: voltage resolution is 0.156 mV/cm, and current resolution is 0.320 microamps/cm. The data format is a left aligned 16 bit 2 complement format. For the current output terminal, the output current range is configurable and can be set to 0 to 20 mA or 4 to 20 mA. For voltage output terminals, the output range can be set to 0 to 10 volts or+/-10 volts. The maximum current load for voltage output is 3 mA.
For current and voltage terminals, the step response to 64% is 24 ms. The resistance load range of the current output is 5 to 750 ohms, 24 volts DC. The absolute accuracy of the voltage terminal is 0.1333% of full scale at 25%, and the absolute accuracy of the current terminal is 0.425% of full scale at 25%. For current terminals, the accuracy drift is 0.0069% of full scale per degree Celsius, and for voltage terminals, the accuracy drift is 0.0045% of full scale per degree Celsius. The 1794-OE4 module is compatible with the 1794-TB3TS and 1794-TBN base units. This module draws 70 mA current from an external power source with a rated voltage of 24 VDC and 150 mA current from an external power source with a rated voltage of 12 VDC. The rated current of the fieldbus is 20 mA. The dimensions of the 1794-OE4 module are 31.8 x 3.7 x 2.1 inches.
