PRODUCT DESCRIPTION
This module is a 5V relay control board with eight channels and optocoupler modules. It meets international safety standards and has isolation trenches between the control and load areas. Each relay has a genuine quality.
The inputs of the 8 Channel 5V Relay Module are isolated to protect any delicate control circuitry.
The module has indicators for power supply and relay status. When the input signal is on, the common terminal and the signal terminal are connected. The module can control appliances with both DC and AC signals, up to 220V AC load.
The module is compatible with a wide range of microcontrollers, such as Arduino, AVR, PIC, ARM, and so on.
The module has a guide rail on the backside, which allows it to be mounted to a suitable location.
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 away;
- 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 8-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
