Description: The OSSR Solid State Relay series are electronic controlled switches, they contain no moving parts. When voltage is applied to the input, a Light Emitting Diode or LED illuminates a Photosensor which controls the internal output circuit. The output circuit is utilized to drive high current loads. The input and output are optically isolated. The OSSR series incorporates a zero crossing circuit which minimizes current and noise surges due to resistive and inductive loads. Optek provides three different electrical configurations of the OSSR series: DC input – AC output, AC input – AC output and DC input – DC output. These configurations meet most industry applications. The OSSRA000XA family comes in a standard panel mount package, commonly known as a “hockey puck” package. The package offers a robust molded epoxy body with exceptional thermal dissipation capability for a long reliable operational life. The input circuit consists of a bridge rectifier circuit which features an AC range from 50 to 250 ADC. The output consists of a Double Triac circuit featuring load current ratings from 10 to 40 Amps and maximum load voltages from 250 to 480VAC with normally open output.

Protective plastic covers are included with shipment of OSSRA series. Installation of the protection cover is necessary.
