3-38 Receiving & Installation
Four programmable opto isolated outputs are available at terminals J1-19 through J1-22.
See Figure 3-44. 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 3-44. 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 3-45.
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.
