OSSRA0009A [Optek]

The OSSR Solid State Relay series are electronic controlled switches with no moving parts. They contain an LED that illuminates a photosensor to control the internal output circuit. The series incorporates a zero crossing circuit to minimize current and noise surges. The OSSRA000XA family comes in a standard panel mount package (hockey puck) with a molded epoxy body for superior heat dissipation. The input circuit features a bridge rectifier with an AC range from 50 to 250 ADC. The output uses a Double Triac circuit with load current ratings from 10 to 40 Amps and maximum load voltages from 250 to 480VAC, normally open. Protective plastic covers are included and installation is necessary.
