These “on-operate” (pull-in) time-delay solid state relays are housed in a single

industry standard package. AC output is controlled by a DC input and has an externally

adjustable time delays. Choices include models with two time-delay ranges (DSD

models: 0.1 sec to 8.3 sec.; DLD models: 1.6 sec. to 133 sec.)

Solid State Control Relays

Crydom’s recognized global leadership in solid-state relays

(SSRs) is taken a step further with our extensive line of solid

state control relays. They can incorporate control circuitry,

intelligence, indication and feedback to an SSR function, further

enhancing the cost-performance benefits for the end user.

Housed in familiar electrically isolated-base packages, many

commonly used power switching/control functions are

incorporated into a single relay. Crydom’s renowned advanced

thermal management techniques are utilized to ensure ease of

mounting and cooling for long life and reliable operation.

Significant cost savings are realized from reductions in design,

volume, cooling, filed maintenance, parts count, acquisition and

inventory costs.

Models SST120 and SST240 control modules gradually apply power to the load when

energized by the control voltage. They must be used with Crydom Series 1 random

turn-on solid state relays. Consult factory for SST wiring diagrams and about use with

480 Vac loads. For a complete set (control module and solid state relay) order

10SST120, 25SST120, etc.
