Classifications of solid state relay?
AC solid state relay can be divided in many ways. Depending on switch methods, there are zero-cross turn on type and random turn on type;
Depending on output switch components, there are triac output type(normal type) and SCR anti-parallel type(enhanced type); Depending on installation methods, there are PCB welding type, panel screw lock type and rail type(with relay socket or cooling fan);
In additional, at input terminal there are constant current source type, wide range input (DC3-32 v), and series resistance current limiting type, etc.

Applications of solid relay?
Solid state relay currently has been widely used in air conditioning, water heater, refrigerator, automatic washing machine, instrumentation, medical equipment, photocopiers; Computer peripheral interface devices, electric furnace heating control system, CNC machinery, remote control system, electric actuators, industrial automation device; Signal light, flasher, light control system; Automatic fire control, security systems, etc. In addition, SSR is frequently used in chemical industry, coal mine or other occasions that need explosion-proof, moisture-proof, anticorrosion.

What is solid state relay? What are the advantages and disadvantages?
Solid-state relay (ab. SSR) is a contactless switching device with relay characteristics, that use semiconductor instead of traditional electric contact as switching device. Single-phrase solid state relay is an active device with four terminals,two of them are input control terminals, the other two are output terminals, opto-isolation between input and output.
When control voltage signal at input side reach a certain current value, the output end shift from off-state to on-state.
Compared with traditional electromagnetic relay, solid state relay is more reliable, with long service life, no noise,no spark, fast switching speed, insulation resistance, vibration resistance, compatible with TTL, DTL and HTL logic circuit. With a small control signal, SSR can directly drive large current electronic switch. Major deficiency: on-state voltage drop(need corresponding cooling measures), off-state leakage current, AC/DC have different applications, less contact sets,besides index of over current, over voltage, voltage rising rate, current rising rate and etc is bad.
