The Allen-Bradley 1746-NO4I Analog Output Module includes connections for user-supplied 24VDC power supplies, and features user-selectable voltage or current inputs, backplane isolation, removable terminal blocks and diagnostic feedback. When external 24VDC power is used, the module only draws 5VDC current from the SLC backplane. If an external 24VDC power supply is required, the tolerance must be 24V ±10% (26.6 to 26.4VDC).
