NOTE: The 1010N-7 Expanded I/O Module auxiliary output signals (Aux Io1 - Aux Io4) geneated from Pgen1, Pgen2, Vo1 and Vo2 are “mirrored” output currents. For example, if Vo1 is a 5 Vdc signal then Aux Io3 will be 12 mA.

NOTE: The method used to create auxiliary current loops makes it impractical to generate the 2 mA fault current produced by the primary 4-20 mA outputs of the meter.
