Power
Z-Worlds expansion boards receive power from the controller over the
+24 V line of the PLCBus. An onboard regulator converts this to the +5V
and the ±12 V reference used by the expansion boards. With no output,
the XP8900 Series expansion boards draw about 30 mA; with all their
output channels operating at maximum current (2mA per channel on
internal power, 7 mA per channel with external voltage), the XP8900
draws 45 mA (75 mA if the external power rails are connected).
