4 Channel Relay Module 5v

The 4-Channel Relay Module allows for controlling up to four high-voltage devices with low-voltage signals. This module is ideal for various applications such as home automation, industrial automation, and robotic control, providing the ability to switch on or off multiple devices independently. 

Key Features:
4 independent relays
Compatible with microcontrollers (Arduino, Raspberry Pi, etc.)
Supports both normally open (NO) and normally closed (NC) contacts
LED indicators for each relay channel
Opto-isolated inputs for protection
Can switch both AC and DC loads
Technical Specifications:
Relay Type: Electromechanical
Operating Voltage: 5V DC or 12V DC (depending on the model)
Trigger Voltage: 5V DC (high or low-level trigger)
Current Consumption: 20 mA per relay (at 5V)
Relay Contact Rating: 250V AC / 10A or 30V DC / 10A per relay
Channel Indicators: LED for each relay

Operating Temperature Range: -40°C to +85°C
Applications:
Home automation systems
Industrial control systems
Robotics
HVAC systems
Security systems
Remote control of devices
Usage:
Power Connection: Connect the VCC and GND pins to a suitable power source (5V or 12V DC).
Control Signal: Connect the input pins to the digital output pins of a microcontroller to control the relays.
Load Connection: Connect the devices to be controlled to the relay output terminals (NO or NC as required).
Programming: Write software to send signals to the input pins to switch the relays on and off as needed.
Caution:
Ensure the total current through the module does not exceed its maximum rating.
Be cautious when working with high voltages to avoid electric shock.
Provide proper insulation and safety measures when dealing with AC loads.
Follow the manufacturer’s guidelines for installation and operation.
Datasheet: For detailed technical specifications, refer to the specific model’s datasheet provided by the manufacturer.
