Dummy Resistor
If the load current is less than the minimum rated value of 20 mA,
there may be a residual voltage across both ends of the load even
if the relay is turned off. Use a dummy resistor as shown to
counteract this. The total current through the resistor and the load
current must exceed 20 mA.
Solid State relay is rated at 1 Amp at 25°C, linearly derated to 0.5
Amp at 55°C. Customer should size fuse accordingly.

Open collector outputs are internally powered at 24 Vdc.
Connecting an external supply will damage the controller.
External relays should be fused between power and relay load.
