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.

Opto In Common
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.
