Opto-isolated Outputs
Four programmable Opto-isolated outputs are available at terminals J1-19 through J1-22. These
outputs can be used to monitor various control conditions.
Powering the Opto-isolated Outputs
The Opto-isolated outputs may be configured as sinking or sourcing. All must be configured the
same. The Opto-isolated outputs will sink up to 60 mA or current each. The maximum voltage from
opto output to common when active is 1.0 VDC (TTL compatible). The Opto-isolated outputs may be
connected in different ways as shown in Figure 2-15.
