Description
New Allen Bradley FLEX Input Output Isolated Output Analog Module 1794-OF4I
Description
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 FLEX I/O analog module. It has 4 isolated analog outputs that 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 1794-OF4I module 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.
