Opto-Isolated Inputs; Opto-Isolated Outputs - Baldor VS1GV21-1B Installation & Operating Manual

5.10 Opto-Isolated Inputs

The equivalent circuit of the nine opto inputs is shown in Figure 5-25. The function of each input depends on the operating
mode selected and are described previously in this section. This Figure also shows the connections using the internal opto
input Supply.
See Figure 5-4 for
connection information.

5.11 Opto-Isolated Outputs

The outputs are opto-isolated and may be configured for sinking or sourcing. However, all must be configured the same. The
maximum voltage from opto output to common when active is 1.0 VDC (TTL compatible). The equivalent circuit for the opto-
isolated outputs is shown in Figure 5-26.
