Special Features

  • Product Description: The relay is one of the most important controls. It's an electrical switch that responds to a signal received from the microcontroller (like in for Arduino or for Raspberry Pi).
  • Features: The control signal DC or AC. 220V AC load can be controlled.Transistor drive to increase the relay coil control pins high impedance.The control pin has a pull-down circuit to prevent malfunction relay vacant.
  • Test instruction: The input and output of the module are electrically isolated. After the correct voltage is supplied, just connect a high level to the input pin header (such as short circuit with VCC) to make the relay pull in, not connect or connect to a low level (such as with GND). short circuit) the relay does not operate.
  • Application: Relays are widely used in remote controls, communication, mechatronic devices, powerful electronics devices, etc. They can also be used to separate high voltage / electric current (such as AC or DC motors or any AC device, etc.) from low voltage / electric current (such as microcontrollers, sensors, etc.).
  • Package includes: You will get 5 x KY-019 Relay Module Board, 1 x 15Pin Female to Male Cable.

Description

Product description:
The driving voltage of the relay coil is 5V, and the input control level can also be within 5V. Module description:
1. Output drive capacity: 250VAC-10A, 125VAC-10A, 30VDC-10A, 28VDC-10A;
2. Easy to use, each group of outputs has a simple 3-wire structure, and 6 output terminals are reserved;
3. The input is directly connected to the IO port of the single-chip microcomputer or the digital circuit, the input high-level relay is pulled in, and the input low-level relay is released;
4. The working voltage is 5V, the pull-in current is about 70mA per channel, with a relay status indicator;
5. The control signal DC or AC , 220V AC load can be controlled .
6. The control pin has a pull-down circuit to prevent malfunction relay vacant
7.There are fixing screw holes for easy installation, the size of the circuit board:34x26/1.32x1.0in, and the weight is 15g;
