3-46 Receiving & Installation
Four programmable Opto-isolated outputs are available at terminals J1-19 through J1-22.
See Figure 3-26. Each output may be programmed to represent one output condition.
The output conditions are defined in
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 3-26. The equivalent circuit for the
Opto-isolated outputs is shown in Figure 3-27.
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.
1. Connect OPTO OUT #1 wires to J1-19 and J1-41.
2. Connect OPTO OUT #2 wires to J1-20 and J1-42.
3. Connect OPTO OUT #3 wires to J1-21 and J1-43.
4. Connect OPTO OUT #4 wires to J1-22 and J1-44.
Each Opto Output is programmed in the Output programming block.
