Transformer Loads
Careful consideration should be given to the selection of the
proper SSR for driving a given transformer. Transformers are
driven from positive saturation of the iron core to negative
saturation of the core each half cycle of the alternating
voltage. Large inrush currents can occur during the first half
cycle of line voltage if a zero-voltage SSR happens to turn on
during the positive half cycle of voltage when the core is
already in positive saturation. Inrush currents greater than 10
times rated transformer current can easily occur. The following
table provides a guide for selecting the proper SSR for a given
transformer rating.
Solenoid Valve and Contactor Loads
All Opto 22 SSRs are designed to drive inductive loads such as
solenoid valves and electromechanical contactors. The built-in
snubber in each SSR assures proper operation into inductive
loads. The following table is a guide in selecting an SSR to
drive a solenoid or contactor.

Control Current Calculation
All Opto 22 DC-controlled SSRs have a control circuit
consisting of 1000 ohms in series with an LED. The LED will
drop 1 volt, so the voltage across the internal resistor will be 1
volt less than the control voltage.
The control current (I
voltage (V

Examples:
3 VDC control voltage:

32 VDC control voltage:

For control voltages above 32 VDC, an external resistor can be
added in series with the SSR to limit the control current. Also, if
the device driving the control current to the SSR is limited, you
can limit the control current by using an external resistor (R
