OVERVIEW

In 1974, Opto 22 introduced the first liquid epoxy-filled line of power
solid-state relays (SSR). This innovation in SSR design greatly improved
the reliability and reduced the cost of manufacturing. At that time, we
also incorporated into our manufacturing process 100% testing under
full-load conditions of every relay we produced.

By 1978, Opto 22 had gained such a reputation for reliability that we
were recognized as the world’s leading manufacturer of solid-state
relays. Through continuous manufacturing improvements and the
same 100% testing policy established over 40 years ago, Opto 22 is

Opto 22 Power Series SSR

still recognized today for the very high quality and reliability of all our
solid-state relays.

DESCRIPTION

Opto 22 offers a complete line of SSRs, from the rugged 120/240/380-volt
AC Series to the small footprint MP Series, designed for mounting
on printed circuit boards. All Opto 22 SSRs feature 4,000 volts of
optical isolation, and most are UL and CSA recognized. The innovative
use of room-temperature liquid epoxy encapsulation, coupled with
Opto 22’s unique heat-spreader technology, are key to mass
producing the world’s most reliable solid-state relays.

PAGE 2

Every Opto 22 solid-state relay is subjected to full load test and six
times the rated current surge both before and after encapsulation.
This double testing of every part before it leaves the factory means
you can rely on Opto 22 solid-state relays. All Opto 22 SSRs are
guaranteed for life.

Accessories for the Power-Series SSRs include a safety cover, a
heatsink, and a matching thermal conductive pad. See page 3.

Power Series SSRs

Opto 22 provides a full range of Power
Series relays with a wide variety of voltage
(120–575 volts) and current options (3–45
amps). All Power Series relays feature 4,000
volts of optical isolation and have a high
PRV rating. Some Power Series relays
include built-in LEDs to indicate operation.
See page 4.

DC Series

The DC Series delivers isolated DC control to large OEM customers
worldwide. All DC control SSRs are LS TTL compatible.

AC Series

The AC Series offers the ultimate in solid state reliability. All AC Power
Series relays feature a built-in snubber as well as zero-voltage turn-on
and zero-current turn-off. Transient-proof models offer self protection
for noisy electrical environments.

Z Series SSRs

The Z Series employs a unique heat transfer
system that makes it possible for Opto 22
to deliver a low-cost, 10-amp, solid-state
relay in an all-plastic case. The push-on,
tool-free quick-connect terminals make the
Z Series ideal for high-volume OEM
applications. Operating temperature:
–40 °C to 100 °C. See page 7.

Printed Circuit Series SSRs

Opto 22’s Printed Circuit Series allows
OEMs to easily deploy solid-state relays on
printed circuit boards. Two unique
packages are available, both of which will
switch loads up to four amps. Operating
temperature: –40 °C to 100 °C. See page 9.

MP Series

The MP Series packaging is designed with a minimum footprint to
allow maximum relay density on the printed circuit board.

P Series

The P Series power relays provide low-profile [0.5 in. (12.7 mm)]
center mounting on printed circuit boards.

HS Series SSRs

The HS Series features an integrated heatsink,
which makes themsocool. These relays have
less thermal resistance inside, so heat
dissipates more easily than in a standard SSR
mounted to the same heatsink. With the
heatsink built-in, you don't have to select
one from a catalog, and installation is much
easier.Includes a DIN-rail adapter. See

page 13.

POWER SERIES SSR ACCESSORIES

Safety Cover

A plastic safety cover (Opto 22 part number SAFETY COVER) is
available for use with Opto 22 Power Series SSRs. The safety cover
reduces the chance of accidental contact with relay terminals, while
providing access holes for test instrumentation.

An optional plastic safety cover can be installed on a Power Series SSR.

SSR-HS Heatsink

Custom designed for the Power Series SSRs, the SSR-HS heatsink
provides excellent heat dissipation when mounted to the SSR with a
matching thermal conductive pad, used in place of silicon grease.
One thermal pad is included with the heatsink. Additional pads may
be purchased in packs of 10 (part number SSR-THERMOPAD).
DIN-rail adapter is included.

Thermal Ratings

The thermal ratings shown in the following graphs were obtained
with an SSR attached to a heatsink using a thermal conductive pad.

Before attaching the SSR, remove the protective film from both sides
of the thermal pad, then place the pad on the heatsink making sure to
align the holes. Secure the SSR to the heatsink with the two 8-32 x
3/8˝ panhead Phillips screws included in the kit. Use 20 in-lb (2.26
