VS 861 SE R I ES

Higher Reliability than Electromagnetic Relays

VS 861210 DC

The DIN-Mountable VS861 Series Solid State Relay with an internal heat sink is the first complete solid state relay available in a modular package.

A SSR (solid state relay) can perform many of the same tasks as an electromechanical relay. 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.

No moving parts

No moving parts to wear or fail

LOAD CONSIDERATIONS

The primary concern when using SSRs is improper heat sinking. 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 cautionar y measures can be taken in high inrush applications to increase the SSR’s versatility, see table at right.

LOAD TY PE CAUTIONARY ACTION

All Load Types

Steady-state Resistance

Verify that the inrush current does not exceed the surge specifications of the SSR.

Consider 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 Lamp

Capacitive

Motors and Solenoids

Use a zero voltage turn-on type.

Verify that the rate of current rise capabilities are not exceeded. Zero voltage turn-on is an effective method for limiting this rate.

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.

Use a zero cross turn-on device; verify that the half cycle surge

Transformers

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.
