Solid-State Relays Panel Mount PackageVAC Input / VAC Output OSSRA0007A thru OSSRA0012A Features: Molded Epoxy package Zero crossing circuit High Input/output Optical Isolation 4k Vrms Superior heat sink package Includes LED indicator Fast switching time Non-contact switch Approval Agency: UL Certification No: E321810 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. Applications: Appliances Temperature controlled systems HVAC temperature control Office equipment Plastic molding Motor controls Packaging industry Industrial Equipment Food processing temperature Light controls systems controls Heater control 1 Moisture OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
