Songle 1 Channel 5V 30A Relay Module with Optocoupler Isolation, High and Low Trigger

This Songle 1 Channel 5V 30A Relay Module with Optocoupler Isolation, High and Low Trigger is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.

The inputs of 1 Channel 5V 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.

A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

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.

Features:

• 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
