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