Opto 22 offers a complete line of solid state relays (SSRs), from the rugged 120/240-volt AC Series to the small footprint MP Series, designed for mounting on printed circuit boards. All Opto 22 relays feature 4,000 volts of optical isolation and are UL and CSA recognized. The innovative use of room temperature liquid epoxy encap-sulation, coupled with Opto 22's unique heat-spreader technology, are key to mass-producing the wo rld'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 both before and after encapsulation. This double testing of every part before it leaves the factory means you can rely on Opto 22 so lid state relays. All Opto 22 SSRs are guaranteed for life. Power Series SSRs 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. DC Series The DC Series delivers isolated DC control to large OEM customers worldwide. AC Series 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. Printed Circuit Series SSRs Opto 22's Printed Circuit Series allowsOEMs 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. 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 for 0.5-inch (12.7mm) center mounting on printed circuit boards.
