OMEGA’s SSRINT Series “intelligent” solid
state relays are fully integrated with heat sink
and DIN rail mounting plate in a space to
saving design. They are touch-safe with LED
input indication. All units come with built-in,

replaceable semiconductor fuses. LED’s
indicate fuse failure. These “intelligent”
relays automatically shut down when in
over-temperature conditions. When returned
to normal operating temperatures, the relay
will turn back on. “Intelligent” relays are
single pole, normally open devices, capable
of millions of cycles of operation. Dual
SCR’s provide a high level of reliability.
Switching takes place at the 0 voltage
crossover point of the alternating current
cycle. Because of this, no appreciable

electrical noise is generated, making SSR’s
ideal for environments where there are
apparatuses susceptible to RFI.
Although these relays have integrated heat
sinks, SSR’s should be located where the
ambient temperature is relatively low, since
the current switching rating is lowered as the
temperature increases (see derating curves).
Another SSR characteristic is a small leakage
of current across the output when the relay is
open. Because of this, a voltage will always
exist on the load side of the device.
