1 Channel Isolated 5V Relay Module Coupling For Arduino PIC AVR DSP ARM

1 channel relay module

  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
