Solid State Relay G3MB-202P-5VDC 4PIN 2A240VAC China Quality
To use this Relay effectively, connect the control input pin (pin 3) to the 5V GPIO pin on your microcontroller, and pin 4 to GND. When a 5V supply is applied, pins 1 and 2 will make contact, allowing current to flow through the connected load.
Relays are used to control high voltage and high current systems with low-voltage control inputs, providing electrical isolation and protection between circuits. Traditional electromagnetic relays operate based on electromagnetism—when the coil is energized, it creates a magnetic field that closes the control circuit; when de-energized, the connection opens.
On the other hand, Solid State Relays (SSRs) utilize photocoupling for switching loads. They offer faster operation than electromagnetic relays, making them ideal for applications such as Switched Mode Power Supplies (SMPS) PWM motor control and servo motor control. In addition to their speed, SSRs are more compact and efficient, making them an excellent choice for space-constrained designs.
