Characteristic of solid state relays 
Solid state relays (SSR for short) is a kind of electronic switch with isolating function and without mechanical contacts, made up of semiconductor and passive element, make use of photoelectric coupler and transformer to electric isolate or electric couple the control circuit (input terminal) and load circuit (output terminal), there isn' t any movable parts inside. The solid state relay not only has switching function that is the same as electromagnetic relay, but also has advantages such as compatible with logic circuit, firm mounted switch, low electromagnet interference or radio frequency interference, long service life and high reliability.

Working principle of solid state relays
1.Solid state relays is a kind of electronic switch that without mechanical contacts, adopting photoelectric device and transformer to electric isolate or signal couple the control circuit (input circuit) and load circuit (output circuit), drive solid power device to make and break or switch the load circuit. Although there are various solid state relays of different specifications in the market, their working principle is similar, and mainly made up of input (control) circuit, drive circuit and output (load) circuit.

2.The input circuit of solid state relays is used to input control signal and work as the triggering signal source. Generally, the input circuit of solid state relays is DC input (like resistant input, the input current will have a linear variation when voltage changes), but some are AC input.

3. The drive circuit of solid state relays includes isolating and coupling circuit, functional circuit and triggering circuit. At present, we adopt photoelectric coupler and high frequency transformer for isolating and coupling circuit. The photoelectric coupler that often used is light-triode, light- bidirectional thyristor and light- diode array (light-volt), etc. The high frequency transformer coupling, under a certain input voltage, a self-oscillation of 10MHz is formed, and transmits the high frequency signal coupling to secondary of transformer through the transformer's magnetic core, and finally drive the trigger circuit. The functional circuit is mainly applied in circuits of solid state relay that require some special functions, it also perfects the drive circuit, includes detection and rectifying, acceleration, protection and display. The trigger circuit is used to supply triggering signal for the output device.

4. The output circuit of solid state relay realize to make or break the load circuit under the control of triggering signal. It usually include power device (chip), some also include absorption circuit that has transient inhibitory action. At present, we often adopt output device such as bidirectional thyristor (Triac), single-directional thyristor (Thyristor or SCR), MOS field effect tube (MOSFET), crystal triode (Transistor) and insulating grid type bipolar transistor (IGBT) for solid state relays.
