Solid-State Relays in Series
In applications requiring 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 following diagram, 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.
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.
