5V 30A 1-Channel Relay Module SLA-05VDC-SL-C 30A

5V 30A 1-Channel Relay Module is a convenient board that can be used to control high voltage, high current loads such as motor, solenoid valves, lamps, and AC load.

This single-channel 5V 30A Relay Module board with LED indicators can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V.

The user can choose the relay control level, can be a high level off, also can be low level and off. The SLA-05VDC-SL-C 30A Relay Module contains a limited flow resistance, can directly use the power supply is a negative control, you can also use the MCU I/O control.

There are two fixed contacts, a normally closed one and a normally open one. When the coil is not energized, the normally open contact is the one that is off, while the normally closed one is the other that is on.

Supply voltage to the coil and some currents will pass through the coil thus generating the electromagnetic effect.

So the armature overcomes the tension of the spring and is attracted to the core, thus closing the moving contact of the armature and the normally open (NO) contact or you may say releasing the former and the normally closed (NC) contact.

After the coil is de-energized, the electromagnetic force disappears and the armature moves back to the original position, releasing the moving contact and normally closed contact. The closing and releasing of the contacts results in power on and off of the circuit.
