Product introduction:

\

1, this module is in line with international safety standard, control areas and load area have the isolation groove;

\

2, USES the loose quality goods relay;

\

3, have power and relay operation instructions, and bright, disconnect the dawn;

\

4, signal input signal, the public end and will often start conduction;

\

5, can be used as a microcontroller development board module, can be used as a home appliance control;

\

6, dc or ac signal control, can control 220 v ac load;

\

7 and one often opened a normally closed contact;

\

8, blue KF301 terminal line more convenient.

\

On high level and low level trigger manner, do not understand friend take a look at:

\

High level refers to the trigger signal and the input voltage between a trigger mode, can understand the positive short circuit for signal input and VCC triggered a way;

\

Low level refers to the trigger signal and the input voltage of between OV trigger mode, can be understood as the signal input end and GND short circuit triggered a negative way
