SOLID STATE RELAY Advantages over Electro-Mechanical Relays
Solid State Relays do not wear out, due to no moving parts or mechanical contacts. Solid state relays are ideal for applications that benefit from many repetitive operations per day. Use of rapid cycling reduces thermal stress and extends the life of most loads, like heaters, extending heater life. Solid state relays have stable operation regardless of age due to lack of wear. A Solid State Relay can be Controlled directly from Logic Circuits. An additional power supply is typically not needed due the the solid state relay’s wide range of control voltage, such as 3 to 32 volts at a few milliamps. An electromechanical contactor requires a drive circuit that often includes a small solid state relay or discrete power device, and the design needs the appropriate voltage power supply for the coil. Though a solid state relay itself typically costs more, the overall cost may be lower due to lower support costs.
Electro-mechanical relays can contain environmentally harmful material, such as mercury. SSR - Our Solid State Relays are environmentally friendly and RoHS compliant (Restriction of Hazardous Substances). Solid state relays do not make audible noise. Solid state relays do not create EMF Bursts (large electrical noise events) because they don't have contacts that arc. Thus, a solid state relay does not create significant magnetic fields and is not vulnerable to them. All of VB Controls solid state relays are CE compliant, which requires having low electronic and magnetic emissions and high immunity to external electromagnetic events. Solid state relays are not affected by gravity and operate in any physical orientation. Solid state relays do not change state due non-destructive vibration or impact. An AC solid state relay is typically five times faster than an electromechanical. DC solid state relays are over one thousand times faster than an Electromechanical. Thus, solid state relays provide superior reliability, performance, ease of use and are environmentally friendly.
