PRODUCT DESCRIPTION
This is a relay control board module with one channel, 12V voltage, and 30A current. It has optocoupler modules that comply with international safety standards and separate the control and load areas. It uses a high-quality single relay.
The inputs of this module are isolated to protect the control circuitry from any damage.
The power supply and relay indicators light up when the module is connected, and turn off when it is disconnected. The input signal, the signal common terminal, and the start conduction are also connected. This module can control appliances with a single-chip microcontroller and can handle both DC and AC signals. It can switch a 220V AC load.
This module is compatible with various microcontrollers, such as Arduino, AVR, PIC, ARM, and others.
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
