4.1.5. User Power Connector (TB303)
This connector provides access to the Ndrive HL’s internal power supply, which may be
used to power external devices (500 mAmps maximum). It also provides a connection to
power the opto-isolated PSO output (see Section 4.1.8., Figure 4-15).

* Total user +5V power from all outputs is limited to 500mA, by an internal re-settable fuse.
4.1.6. Opto-Isolated Outputs (TB304)
The outputs are software configurable via the DriveIOConfig axis parameter as sourcing
or sinking, and are driven by a PS2802-4 opto-isolator that is rated for 40 volts DC
maximum and up to 80 mA/channel, not to exceed 90 mW per channel. Figure 4-10 and
Figure 4-11 illustrate how to connect to the output in current sinking and current
sourcing modes, respectively.
The connection must always be made to both the Output
Common Plus and Output Common Minus connections to
prevent glitches on the outputs, as shown in the wiring
diagrams in Figure 4-10 and Figure 4-11.
