The Allen-Bradley 1794-OF8IH is a FLEX I/O HART enabled analog output module with 8 isolated current outputs for 4…20 mA or 0…20 mA and 16-bit resolution (unipolar). It draws 450 mA at 24V DC and is rated for 0…55 °C (32…131 °F). FLEX I/O modules plug into a terminal base unit that carries the field wiring, so a module can be removed and inserted under power without disturbing field wiring; one FLEX I/O adapter communicates with up to eight I/O modules.
