Allen Bradley 1794-OF4I Series A Flex I/O Isolated Output Analog Module. The Allen-Bradley 1794-OF4I Flex I/O Isolated Output Analog Module has 4 Isolated Outputs, a 15 bits Resolution, and a Digital-to-Analog Converter Conversion Type. It also operates with a 3mA max. Current Load on Voltage Output and a 50mA FlexBus Current. The Allen-Bradley 1794-OF4I is a 24 Volts DC FLEX I/O analog module.Outputs and 4 key switch positions. These outputs can be connected to devices that use category 2-, 3-, or 4- wires. This module is compatible with several terminal base units, namely the 1794-TBT, 1794-TB3, 1794-TB3TS, 1794-TB3S, 1794-TBNF, and the 1794-TBN. It can be mounted using a DIN rail or a panel, it has an open enclosure, and it measures 3.7 x 2.6 x 3.7 inches.
The external DC voltage range of the. Is 19.2 to 31.2 Volts DC, including the 5% AC ripple.
It also has an external DC power supply current of 210 mA at 24 Volts DC. Its maximum overload is 30 Volts or 32 mA continuous in one channel at a time. This module has a maximum 3 mA current load on voltage output and a 0 to 750 resistive load on voltage output. Its output current ranges are 4 to 20 mA and 0 to 20 mA. Both of these ranges are user-configurable.
The module's output voltage varies from +/-10 Volts, +/-5 Volts, 0 to 10 Volts, and. 0 to 5 Volts, all of which are also user-configurable.Both the voltage and current terminals have 0 output until the module is configured. The 1794-OF4I has a maximum power dissipation of 4.7 W at 31.2 Volts DC and a maximum thermal dissipation of 16 BTU/hour at 31.2 Volts DC. The module's isolation voltage is dependent on the terminal base unit it is connected to; it is 250 Volts continuous when using a 1794-TBN base unit and 120 Volts continuous when using other compatible base units.
The FlexBus voltage of the module is 5 Volts DC, while the FlexBus current is 50 mA. It has a resolution of 15 bits + sign, 0.320 mV/cnt (voltage), and 0.656 mA/cnt (current). It also has an update rate of 2.5 or 5 milliseconds for all channels and a <25 µs step response at 63% of full scale.
Both the voltage and current terminals have an absolute accuracy of 0.1% full scale at 25 degrees Celsius but they have different accuracy drifts with temperature, since it is 0.0012% full scale per degree Celsius for the voltage terminal and 0.0025% full scale per degree Celsius for the current terminal. The conversion type for the 1794-OF4I is digital-to-analog.
