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 100°C.

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
