XP8600 Getting Started s 19
Power
Z-Worlds expansion boards receive power from the controller over the
+24 V line of the PLCBus. An onboard regulator converts this to the +5V
and the ±10 V reference used by the expansion boards. With no output,
the XP8600 expansion boards draw about 30 mA; with all their output
channels operating at maximum current (22 mA per channel), the XP8600
draws 75mA.
