⁽¹⁾ Require no LocalBus current as controllers are powered separately by the system power supply.

⁽²⁾ For Series 2 cards in redundant applications, the numbers shown in the table are for each card of a redundant pair. For example, the power required for a redundant pair of Series 2 DO cards is .300 A at 12 VDC and a maximum of 3 A at 24 VDC for 24 VDC field power.
