Digital Outputs
Opto Isolated Outputs
Two programmable opto isolated outputs are available at terminals J4-19 and J4-20. See
Figure 3-38. Each output may be programmed to represent one output condition. The
output conditions are defined in Section 4 of this manual.
The opto isolated outputs may be configured for sinking or sourcing 60 mA each, as
shown in Figure 3-38. However, both 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 3-39.
If the opto outputs are used to directly drive a relay, a flyback diode rated at 1A, 100 V
(IN4002 or equivalent) minimum should be connected across the relay coil.
Each opto output is programmed in the Output programming block.
