← Back to productsProduct overview
The Allen-Bradley 1794-IF4I is a FLEX I/O isolated analog input module with 4 inputs with channel-to-channel isolation for 4…20 mA, 0…20 mA, ±20 mA, ±10V, 0…10V, ±5V or 0…5V, for 2-wire, 3-wire and 4-wire sensors. It draws 80 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.
