Solid State Relays
Opto 22 offers a complete line of solid-state
relays, from the rugged 120/240-volt AC Series (picture-middle) to the
small footprint MP Series (picture-right) , designed for mounting on printed
circuit boards. All Opto 22 relays feature 4,000 volts optical isolation
and 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. Every Opto 22 solid-state relay is subjected to full load
test and six times the rated current surge 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
Power Series SSR
Power Series Solid-State Relays
Opto 22 provides a full range of Power Series relays with a wide variety
of voltage (110–575 volts) and current options (3–45 amps). All Power Series
relays feature 4,000 volts of optical isolation, and have a high PRV rating.
The DC Series delivers isolated DC control to large OEM customers worldwide.
The AC Series offers the ultimate in solid-state reliability. All AC
Power Series relays feature a built-in snubber and zero voltage turn on.
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.
Z Series SSR
MP Series SSR
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.
The MP Series packaging is designed with a minimum footprint to allow
maximum relay density on the printed circuit board.
The P Series power relays provide low-profile for 0.5-inch (12.7mm)
center mounting on printed circuit boards.
