1. the module is compliant with international safety standards, control and load areas isolation trenches;
2. a single relay a genuine;
3. power supply and relay instructions, lit, disconnect is off;
4. input signal, signal, common Terminal and start conducting;
5. can be used as a single chip modules can be used for appliance control;
6. DC or AC signal, control, you can control the 220V AC load;
7. there is a normally open and one normally closed contact;

Specification:

• One normally closed contact and one normally open contact
• Triode drive, increasing relay coil
• High impedance controller pin
• Pull-down circuit for avoidance of malfunction
• Power supply indicator lamp
• Control indicator lamp
• Channel: 1 channel
• Relay Voltage: 5V

Note on the high level and low level triggered mode, friends who do not understand, have a look:

• 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 input terminal and Earth OV trigger, can be understood as signal input terminal and the GND negative electrode short circuit triggered a way  1-channel relay module connection
