+5V ENC PWR (Alternate Encoder Power)
Typically, feedback devices are powered up through the X1-X8 connectors on the Geo Brick Drive using
the internal +5VDC power supply. In some cases, feedback devices consume power excessively and risk
of surpassing the internal power supply limitation.
This connector provides an alternate mean to power-up the feedback devices (+5V only) if the budget
exceeds the specified thresholds.

Note
Encoders requiring other than +5VDC power must be supplied
externally, and NOT through the X1-X8 connectors NOR through this
+5VDC connector.

X X X
The add-in board (any non-zero digit in the highlighted part number field) for MACRO and special
feedback requires an additional ~ 0.5A (+5V power). This alters the total power available for encoders.
The newer models of the Geo Brick Drive have a stronger power supply which can handle more (+5V)
power drain. The following tables summarize the +5V power available for encoder devices (X1-X8):
Caution
The maximum current draw out of a single encoder channel must not
exceed 750 mA.
