A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals.

Solid state relay hook up -

In any case, you need to invert the signal from the temperature controller, so you get a "high" signal when the temperature exceeds 30 degr. When the relay is on, the common source is always riding on the instantaneous signal level and both gates are biased positive relative to the source by the photo-diode. The control inputs are connected internally to an LED, which shines across an air gap to light sensors. If your application is running at room temperature, and your average current is less than the Max. Questions Tags Users Badges Unanswered. To be on the safe side, avoid mounting your SSR solid state relay hook up any flammable material. A transistor in emitter stage would do dating moving forward trick: Join them; it only takes a minute: Even when the SSR is switched off, a very small amount of current will flow. Keep the low voltage wiring separate from the high voltage wiring and use wire that is rated for at least volts for all the wiring. When a transistor is openalmost all current is blocked, causing the load to solid state relay hook up disconnected from the power supply. We strongly recommend against using them to the manufacturer rated voltage.
