FAQ
A Solid-State Relay (SSR) is a totally electronic device that depends on the electrical, magnetic and optical properties of semiconductors to control the flow of current in a circuit. SSRs are an alternative to Electro-mechanical relays offering enhanced electrical performance and reliability.
Solid State Relays have several benefits against their electromechanical counterparts. The following are only a few of them:
- Extremely Long Life
- Silent Operation
- No Moving Parts Eliminates Arcing & Switch Bounce
- Resistant to Shock and Vibration
- Reliable Operation in Harsh Environments
- Operation is Not Dependent Upon Orientation
- Low Input Power Consumption
- Reduced Electromagnetic Interference
Initial cost of purchase is high for SSRs. But due to their long-life capacity and ability to handle heavy loads, SSR cost works out economically in the long run.
When selecting a Solid-State Relay several aspects must be taken into consideration, such as:
- Load Voltage
- Load Current
- Input Voltage
- Ambient Temperature
- Mounting Style (PCB, Plug-in, Panel or DIN Rail mounting)
- International Approvals (UL, CSA, VDE, TUV, etc.)
SSRs offer a high reliability alternative to electro-mechanical relays when switching a wide range of loads such as motors, heaters, solenoids, lamps, compressors, fans, among others, in applications as diverse as:
- Coffee machines
- Commercial / Industrial cooking equipment
- Packaging machinery
- Plastic machinery (extrusion/thermoforming)
- HVAC & R systems
- Lighting control systems
- Lifts and escalators
- Medical equipment
