If the load current is less than the minimum rated value of 20 mA, then there may be residual voltage across both

1ends 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 the load must exceed 20 mA. Solid State Relays are zero-crossing type.

Solid State relays are rated at 1 Amp at 25°C and derated linearly to 0.5 Amp at 55°C. Customer should size

2fuse accordingly. Use Fast Blo fuses only.

3Electromechanical relays are rated at 5 Amps @ 120 Vac or 240 Vac or 30 Vdc. Customer should size fuses accordingly. Use Fast Blo fuses only.

See Table 2-5for relay terminal connections for other Output Algorithm Types.
