DATA SHEET
Solid-State Relays In Series
In applications requiring greater current rating at higher voltage,
two Opto 22 SSRs may be operated in series for double the
voltage rating. The built-in snubber in each SSR assures proper
voltage sharing of the two SSRs in series. In the diagram below,
two 240-volt, 45-amp SSRs are connected in series for operation
on a 480-volt line. The control is shown with a parallel hook-up
but it should be noted that a serial connection can also be
implemented.

Applications
Lamp Loads
Since all Opto 22 SSRs are zero voltage switching, they
are ideal for driving incandescent lamps because the
initial inrush current into a cold filament is reduced.
The life of the lamp is increased when switched by a
zero voltage turn on SSR. The following table is a guide
to selecting an Opto 22 SSR for switching a given
incandescent lamp.

SOLID-STATE RELAYS
Heater Loads
Care should be taken in selecting a SSR for driving a heater load if
the load is cycled on and off in a continuous manner as might occur in
a temperature control application. Constant cycling can cause thermal
fatigue in the thyristor chip at the point where the chip bonds to the
lead frame. Opto 22 employs a thick copper lead frame for mounting
the SCR chips in the power series SSRs to eliminate thermal fatigue
failures. In addition, Opto 22 recommends operating any SSR at 75%
rated current for cycling heater loads to ensure complete reliability.
The following table is a guide to selecting the proper SSR for a given
heater load.
