3.3 Power Connection
The unit requires 24V dc ±20% at approximately 700mA (max.) for the logic power supply unit.
The unit also takes 12-24V dc ±20% at approximately 400mA (max.) for the isolated outputs and
12V to 24V dc or -12V to -24V dc ±20% at approximately 200mA for the isolated digital inputs and
fast interrupts.

Figure 3-4: NextMove BX Power Supply Unit
The unit has an on board power supply to provide the following:
•
5V regulated output for incremental encoders.
• +/-12V output, 5V output for general use. Note that these must not be used for machine
I/O. Do not attempt to draw more than 200mA from the 12V rails and no more than
650mA from the 5V (including the encoders).
If the encoders require more than 650mA total, some of them (or all) must be powered from an
external 5V supply. This additional supply must NOT be connected to the NextMove BX 5V
supply.
