← Back to productsProduct overview
The Allen-Bradley 1794-OF4I is a FLEX I/O isolated analog output module with 4 isolated outputs for 4…20 mA, 0…20 mA, ±10V, 0…10V, ±5V or 0…5V, with 15-bit + sign resolution, for 2-wire, 3-wire and 4-wire devices. It draws 210 mA at 24V DC. 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.
