1 Channel Relay Module- Low Level

100% of 100
Price $5.99


When a low level is given to SIG, the PNP transistor is energized; then the coil of the relay thus is energized and the normally open contact is closed, with LED lighting up. If a high level is given to SIG, the PNP de-energized; thus, the relay returns to the original state and the LED goes out.


  • A relay module to control high voltages with a low voltage by connecting to an MCU.
  • Support control of DC and AC signals (AC 220V load)
  • Working voltage: 5V; PCB size: 2.0 x 4.3 cm
  • With power light and signal output indicator
  • A 3-pin anti-reverse cable included


The module can be used as a development module on an MCU or for control of household appliances.
