| 3 | Control Signal Input |
| 4 | Power Output (+) |
| 5 | Power Output (-) |
In this example, terminal 1 is connected to the positive side of the power source, while terminal 2 is connected to the negative side. Terminal 3 receives the control signal, which determines whether the relay is activated or not. Terminals 4 and 5 are used for the power output, which connects to the load that the relay controls.
By understanding the wiring diagram, one can ensure that the Songle relay is wired correctly and functions as intended. It is important to follow the diagram precisely and double-check all connections to avoid any potential issues or malfunctions.
Songle relay pinout explained
A Songle relay is a commonly used component in electronic circuits to control high-powered devices or circuits using a low-power signal. Understanding the pinout of a Songle relay is essential for properly wiring it in a circuit.
The Songle relay typically has five pins: two for the coil and three for the switch contacts. The coil pins are usually marked as “Coil +,” “Coil -,” or “A1” and “A2,” indicating the polarity of the coil. It is important to connect the coil pins to an appropriate power source with the correct polarity for the relay to function properly.
The switch contact pins on the Songle relay are usually marked as “NO” (normally open), “NC” (normally closed), and “COM” (common). The common pin is connected to one of the other two pins depending on the relay’s state. When the relay is activated, the common pin is connected to the normally open pin, and when the relay is deactivated, the common pin is connected to the normally closed pin.
To use a Songle relay in a circuit, the coil pins should be connected to a power source, typically a microcontroller or a transistor, that can provide the necessary current to activate the coil. The switch contact pins can then be connected to the desired circuit or device that needs to be controlled.
It is important to consult the datasheet or documentation of the specific Songle relay model being used to ensure the correct pinout configuration. Additionally, care should be taken to avoid exceeding the maximum voltage and current ratings of the relay to prevent damage or malfunction.
