Solid State Relays 4-Pin SIP PackageVDC InputVAC/VDC Output OSSRD2001D and OSSRD2002A Features: Molded Epoxy package Zero crossing circuit High Input/output Optical Isolation 4k Vrms Small size and light weight Can be installed directly on the P.C. board 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 OSSRD2001D and OSSRD2002A are offered in a standard 4-pin SIP, Single In-Line Package, for PCB mounting applications. The package offers a light weight, compact and robust molded epoxy body with extended operating temperature range of up to 100C. The OSSRD2001D input circuit features a DC range from 4 to 24 VDC. The output consists of a photo darlington circuit featuring a load current rating of 3 Amps and a maximum load voltage of 100VDC and 30 Watts with normally open output. The OSSRD2002A input circuit features a DC range from 4 to 32 VDC. The output consists of a Triac circuit featuring a load current rating of 3 to 40 Amps and a maximum load voltage of 250VAC with normally open output. Applications: Temperature controlled systems Office equipment Motor controls Industrial Equipment Light controls systems Heater control Appliances HVAC temperature control Plastic molding Packaging industry OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
