12V Relay Module DC 12V Four Channel Isolated Relay Control Module With Screw Terminal For Arduino 4 Channel DC12V With Optocoupler Protection

It is a 4 Channel Isolated 12V 10A Relay Module, A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it. It is also able to control various appliances and other types of equipment with a large current.

Relay output maximum contact is AC250V 10A and DC30V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.

Ready to get switching on your Raspberry Pi?! This neat relay module features 4 x 12V relays rated at 10A/250V each. It is designed to switch up to 4 high currents (10A) or high voltage (250V) loads with the help of microcontroller!

Each relay can individually switch on/off by an opto-isolated digital input, which that can connect directly to a microcontroller output pin. It only requires a voltage of approx. 1.0V to switch the inputs on but can handle input voltages up to 12V. This makes it ideal for 1.0V to 12V devices.

 Overview:

• One normally closed contact and one normally open contact
• Triode drive, increasing relay coil
• High impedance controller pin
• Pull-down circuit for the avoidance of malfunction
• Power supply indicator and Control indicator lamp
• Power supply and relay instructions, lit, the disconnect is off;
• The input signal, signal, common Terminal and start conducting;
• Useful for appliance control;
• DC or AC signal, control, you can control the 220V AC load;
• There is a normally open and one normally closed contact;
• The module is compliant with international safety standards, control and load areas isolation trenches.

• Size: 75mm (l) x 55mm (b) x 19.3mm (h)
• Weight: 58g
• P.C.B Color: Blue

How to connect:

The connections to your Arduino (or microcontroller) side:

• VCC – supply voltage. 12V from my Arduino.
• IN1 – set to HIGH to set the relay to its “default” state, set to LOW to switch the relay to its alternate state
• IN2 – same as IN1, but controls the second relay on the board
• IN3 – same as IN1, but controls the second relay on the board
• IN4 – same as IN1, but controls the second relay on the board
• GND – ground

Application:

• Smart home control
• Industrial sector
• Fan/lighting control
• 5-12 VDC automotive application
• support all MCU control.
• the industrial sector;
• PLC control;
• smart home control;

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 the signal input terminal and the GND negative electrode short circuit triggered away  1-channel relay module connection
