The Allen-Bradley 1794-OF4I is a FLEX I/O analog module distinguished by its four isolated analog outputs, compatible with various terminal base units including 1794-TBT and 1794-TB3. Designed for seamless integration, it can be conveniently mounted on a DIN rail or a panel, offering an open enclosure with dimensions of 3.7 x 2.6 x 3.7 inches. Supporting an external DC voltage range of 19.2 to 31.2 volts, and powered by an external DC power supply current of 210 mA at 24 volts, this module allows user-configurable output currents ranging from 4 to 20 mA and 0 to 20 mA, as well as output voltages like ±10 volts and 0 to 10 volts. With a digital-to-analog conversion resolution of 15 bits plus sign, an update rate of 2.5 to 5 milliseconds across all channels, and exceptional accuracy ratings, the 1794-OF4I is an optimal choice for robust and precise industrial automation applications.
