The SSR differs in that it contains no moving mechanical parts. It is essentially an electronic device that relies on the electrical, magnetic, and optical properties of semiconductors and electrical components to achieve its isolation and relay switching function.

The type of load current should be evaluated when considering an SSR as a switching option. SSRs alone are not compatible with high inrush currents, but cautionary measures can be taken in high inrush applications to increase the SSR’s versatility, see table at right.LOAD TYPECAUTIONARY ACTIONAll Load TypesVerify that the inrush current does not exceed the surge specifica-tions of the SSR.Steady-state ResistanceConsider thermal management. Assure device temperature will remain in safe operating area.DC (Inductive)Place a diode across the load to absorb surges during turnoff.Incandescent LampUse a zero voltage turn-on type.Capacitive Verify that the rate of current rise capabilities are not exceeded. Zero voltage turn-on is an effective method for limiting this rate.Motors and Solenoids Use a current shunt and oscilloscope to examine the duration of the inrush current. Verify that back EMF does not create an overvoltage situation during turn-off.TransformersUse a zero cross turn-on device; verify that the half cycle surge capability is not exceeded. Rule of thumb: select an SSR with a half cycle current surge rating greater than the maximum applied line voltage divided by the transformer primary resistance.MODELRELAYAMPERAGE RATINGINPUT VOLTAGE SWITCHING DEVICESWITCHING VOLTAGESWITCHING TYPEULCEVS861210DCSPST, N.O.10 A3 to 32 VdcSCR24 to 280 VacZero Cross••VS861210AC10 A90 to 280 Vac, 80 to 140 VdcSCR24 to 280 VacZero Cross••VS861208DC8 A3 to 32 VdcTriac24 to 280 VacZero Cross••VS861208AC8 A90 to 280 Vac, 80 to 140 VdcTriac24 to 280 VacZero Cross••VS861208DD8 A3.5 to 32 VdcMOSFET3 to 150 VdcDC Switching••ORDERING INFORMATIONRelays | VS861 SeriesHQ0001855.F 0117Next >
