NOTE
1. When used for the load less than
rated
In case of the load current less than
rated, malfunction may result from the
residual voltage across the both ends of
the load even if the solid state relay is
turned off. Use a dummy resistor as a
countermeasure.
The total of the current through the
resistor and the load current must exceed
the min. rated load current.

In case the dummy resistor is not used,
keep in mind that the residual voltage
becomes as follows:
Example:
For the inductive load by the 20 mA load
current and the 200 V AC load voltage,
the load impedance becomes 10 k Ω and
Ve/V = 14% is estimated from the right
above graph. Accordingly, the 28 V
voltage remains across the both ends of
the load when the solid state relay is
turned off.
