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.The relay may be designed to switch either AC or DC to the load. It serves the same function as an electromagnetically relay, but has no moving parts.
Input/Output
- 3-32VDC — 24-280VAC
- 3-32VDC — 24-480VAC
- 90-280VAC — 24-280VAC
- 90-280VAC — 24-480VAC
- 10A,25A,40A,50A,70A
Relative advantages of solid state as against electromechanical relays.
- Totally silent operation.
- SSRs switch faster than electromechanical relays;
- Increased lifetime, even if it is activated many times, as there are no moving parts to wear and no contacts to pit or build up carbon.
- Output resistance remains constant regardless of amount of use.
- No sparking, allows it to be used in explosive environments, where it is critical that no spark is generated during switching.
- Much less sensitive to storage and operating environment factors such as mechanical shock, vibration, humidity, and external magnetic fields.
Applications for Solid State Relays:
Solid state relays are ideal for repetitive applications due to the absence of moving parts. Some applications for solid state relays are:
- Medical
- HVAC
- Professional food equipment
- Theatrical lighting
- Industrial machinery
- Control panels
- Elevators and lifts
- I/O interfaces
