Solid State Relay. This is the circuit diagram of solid state relay. In reality, it is not a relay after all. There’s no ‘relay’ found, just the electronics circuit which does the switching. It operates a similar way as a relay; it is possible to use a low voltage to switch a higher voltage or better than ordinary relay.
Solid State Relay Solid state relay is a hybrid circuit, normally composed of an optocoupler which isolates the input, a trigger circuit that detects the zero crossing of the line current and a triac or similar device that acts as a circuit breaker.
Solid State Relay Wiring Diagram. Variety of solid state relay wiring diagram. A wiring diagram is a simplified traditional pictorial depiction of an electrical circuit. It shows the parts of the circuit as streamlined forms, as well as the power as well as signal connections between the devices.
Solid state relay (SSR) is an electronic switching device made of semiconductors that switch (On & Off) a high voltage circuit using a low voltage at its control terminals. Unlike EMR (Electromagnetic relay) that has a coil & mechanical switch (physical contacts), the SSR relay uses Optocoupler to isolate the control circuit from the controlled circuit.
In contrast to electromechanical relays, which consists of moving parts and magnetic flux, a Solid State Relay or SSR doesn’t consist of any moving parts. A Solid State Relay consists of semiconductor devices like transistors, thyristors, SCR’s or TRIACS to achieve the switching operation.
DC DC SSR Solid State Relay. This is a DC Input DC Output SSR Solid State Relay. It was made for Printing or Photo Processing Equipment. It has an optical isolation and can be used for inductive loads. The R1 Limits current and Z1 and D1 protects.
The internal schematic of the solid state relay is shown in the data sheet, but showing all of the internal components in the Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
Consider the output waveform diagram below of a typical AC solid state relay. Solid State Relay Output Waveform With no input signal applied, no load current flows through the SSR as it is effectively OFF (open circuited) and the output terminals see the full AC supply voltage.
The electrical separation between the input control signal and the output load voltage is accomplished with the aid of an opto coupler type Light Sensor. The Solid State Relay provides a high degree of reliability, long life and reduced electromagnetic interference (EMI), (no arcing contacts or magnetic fields),...
Current voltage characteristics of a BJT. Image adapted from Solid state Relay Handbook with Applications by Anthony Bishop. When the switching device of an SSR is on (see point A above), there is a voltage drop across the SSR output terminals which is called the “on state voltage drop”. This parameter is given in the device datasheet.
