Description
1 Channel Isolated 5V Relay Module Coupling For Arduino PIC AVR DSP ARM
- the module is compliant with international safety standards, control and load areas isolation trenches;
- a single relay a genuine;
- power supply and relay instructions, lit, disconnect is off;
- input signal, signal, common Terminal and start conducting;
- can be used as a single chip modules can be used for appliance control;
- DC or AC signal, control, you can control the 220V AC load;
- 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
