Opto-Isolated Outputs Four programmable Opto-isolated outputs are available at terminals J1-19 through J1-22. See Figure 3-29. Each output may be programmed to represent one output condition. The output conditions are defined in Table 4-4of Section 4 of this manual.

The Opto-isolated outputs may be configured for sinking or sourcing 50 mA each. However, all must be configured the same. 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 3-29. The equivalent circuit for the Opto-isolated outputs is shown in Figure 3-30.

If the opto outputs are used to directly drive a relay, a flyback diode rated at 1A, 100 V (IN4002) minimum should be connected across the relay coil. See Electrical Noise Considerations in Section 5 of this manual.

Each Opto Output is programmed in the Output programming block.
