Product Insights: Crydom Generation 4 Solid State Relays

Crydom is now offering its improved line of panel mount Solid State Relays.

The industry standard panel mount relay has been in production at Crydom for over 40 years and is universally accepted as the global benchmark for panel mount SSRs. 

For this Arrow Product Insights, we present Crydom’s 4th generation of panel mount Solid State Relays.   Crydom is now offering it’s improved line of panel mount Solid State Relays.  The industry standard panel mount relay has been in production at Crydom for over 40 years and is universally accepted as the global benchmark for panel mounts SSR’s.  Crydom’s new Generation 4 is an extensive redesign of their entire single face panel mount Solid State Relays, including some of their most popular product series of both AC and DC output models on both the IP00 and IP20 versions. 

This redesign includes some significant improvements includes some significant improvements over the previous Generation 3 design, while maintaining the same ratings, general features and basic physical size.  Mechanical improvements include a redesigned housing with antirotation wire capture classic barriers on both input and output terminals to better capture solid and stranded wires while also allowing the use of ring or fork terminals.  The improved SEMS screw and washer provide significantly higher wire pullout strength in single or dual wire capability. 

Thermal performance improvements are achieved with DBC, direct bond copper technology.  DBC insulators are used on the output stage, which reduce thermal impedance therefore, lowering output stage temperatures, thus, increasing reliability.  Direct output lead frame termination provides significantly greater contact surface area, resulting in lower power dissipation and overall improved reliability of the relays. Stress in epoxy free construction reduces weight by thirty percent, which lowers freight costs and results in an environmentally greener product. 

AC output models now feature regulated control inputs and an improved circuit performance utilizing an optical triad coupler, resulting in improved DNC noise immunity and reduced output off state leakage current.  CD output models feature an improved trigger circuit with higher PWM frequency capabilities and lower power dissipation when switching off. 

Crydom’s Generation 4 SSR’s features major improvements in termination, wiring option, circuit performance, and reliability.  State of the Art design, materials, and assembly process make Crydom’s Generation 4 truly the best panel mount Relay in the world.
