PRODUCT DESCRIPTION
This module is an 8-channel 5V relay control board featuring optocoupler isolation. It complies with international safety standards and includes isolation trenches between the control and load sections, ensuring reliable performance from high-quality relays.
The inputs of the 8-Channel 5V Relay Module are isolated to protect sensitive control circuitry. It includes indicators for power supply and relay status: when the input signal is active, the common terminal connects to the signal terminal. This module can handle both DC and AC loads up to 220V AC.
Compatible with various microcontrollers such as Arduino, AVR, PIC, and ARM, the module also features a guide rail on the backside for easy mounting in 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
