Solid State Relay
Protection you can rely on
Our solid-state relay range consists of HEXFET® Power MOSFET and IGBT output photovoltaic relays plus photovoltaic isolators that give designers the flexibility to create their own relays.
The solid state relays (SSRs) are on/off remotely controlled switches with complete galvanic isolation from input to output. No power supply is needed on the output. Using a relay allows for low-power control (e.g. from a microprocessor) over a high-power signal (e.g. switching of AC and DC loads) while providing galvanic isolation between the logic part of the circuitry and high power signals. This isolation provides users with protection from electrical shocks and protects electronics (e.g. microprocessors) from damage from high-voltage spikes.
Solid state relays are divided into two main sub-groups:
- Photo Voltaic Isolators (PVI)
- Isolated, low power DC voltage sources capable of driving MOSFET or IGBT gates directly
- Photo Voltaic Relays (PVR)
- PVI plus power MOSFET or IGBT
