What is the difference between the solid relay output and the relay output?
Solid state output using thyristor conduction, contact output is the mechanical switch.
Solid-state output using SCR, can be non-contact, fast response, can be easily used optocoupler and technology for anti-interference and electricity isolation. And longer life, the relay can not reach the above indicators.
You refer to the solid state relay output is the solid state relay output, the relay output is the electromagnetic relay output. In the final analysis, the key to this problem is the difference between solid state relays and electromagnetic relays.
Solid state relay is a microelectronic circuit, discrete electronic devices, power electronic power components composed of non-contact switch. Use and electromagnetic relays almost.
Solid state relay is superior to the electromagnetic relay is:
Input power is small, high sensitivity, control power is small, the logic circuit is compatible.
Resistant to mechanical shock (which is very important, electromagnetic relay vibration may be misleading)
Has a good moisture-proof mold anti-corrosion properties
Electromagnetic compatibility, low noise and high operating frequency characteristics.
