Time Proportional
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 relays are rated at 0.5 amps. Customer should size fuses accordingly. Use Fast Blo
fuses only.
Electromechanical relays are rated at 5 Amps @120 Vac or 30 Vdc and 2.5 Amps at 240 Vac.
Customer should size fuses accordingly. Use Fast Blo fuses only.
WARNING: Only connect Vac to solid
state relays.
