- The use of high-quality single-pole double-throw relay, a common, a normally open and a normally closed end;
- Using optocoupler isolation, anti-jamming is good
- With the status indicator, the West River when the light is on, the release of the indicator light off;
- System power supply (VCC), relay power supply (JD_VCC) jumper cap optional;
- Control zone and the load zone isolation groove design, double FR-4 circuit board, high-end patch technology, product performance is stable and reliable.
- It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.
- High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way;
- Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 1-channel relay module connection.
