This 1 Channel Relay Module 30A with Optocoupler, Isolation 12V Supports, High and Low Triger is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.
The inputs of 1 Channel 12V 30A Relay Module are isolated to protect any delicate control circuitry.
The power supply and relay instructions, lit, a disconnect are off. The input signal, signal, common Terminal and start conducting. 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.
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 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.
- High impedance controller pin
- Pull-down circuit for the avoidance of malfunction
- One normally closed contact and one normally open contact
- Triode drive, increasing relay coil
- Power supply indicator lamp
- Control indicator lamp
- With 4 fixed screw holes, hole diameter 3.1mm, convenient installation, and fixation
