When the logic of the protection or control circuit is no longer limited to the results of wiring individual relay functions together but is the composite of the user defined logic internal to the relay devices and the external wiring between devices the limitation of the dashed lines to depict the overall protection circuit logic has become unacceptable for many users.... An arduino can only supply so much current, usually around 20mA, enough to drive an LED. Any circuit that needs more than 20mA will need some sort of current amplifier or buffer hence the transistor. The relay requires 30mA to pull-in. If you drove the relay directly from the Arduino pin and simply

How To Read A Relay Schematic

Simplified solid state relay schematic Bench Testing a Solid State Relay A multimeter determines impedance by injecting a small amount of voltage through its probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output

  • To further illustrate how a relay works, let's look at it as it functions within an electrical circuit. First, we need to know the symbols for the parts of a relay. The illustration below shows the 3 symbols used in an electrical schematic to represent the 3 parts: The coil, a normally open contact and …
  • The schematic symbols used to represent relays are the same as those for manually operated switches, except that relay symbols often include a solenoid coil. There are several possible ways of depicting the solenoid coil.

  • Draw a schematic diagram for such a circuit, showing the power supply (battery symbol), relay, and resistor. Explain how the resistor’s value would be calculated, along with the calculated value in ohms.
