(2-Channel 5V Relay Module with Optocoupler High/Low Level Trigger)

65.00 EGP

A two-channel electromagnetic relay module used for the safe control of high-voltage and high-current electrical devices and equipment using precise, low-voltage control signals from a microcontroller (such as an Arduino, ESP32, STM32, or Raspberry Pi). Technical Specifications: Operating Voltage (VCC): 5V DC Relay Model: Songle SRD-05VDC-SL-C Relay Ratings: AC Current: Up to 250V/10A (or 125V/10A) DC Current: Up to 30V/10A (or 28V/10A) Optocoupler Isolation: Features built-in optocouplers to completely isolate the low-voltage control circuit from the high-voltage circuit, protecting the microcontroller from back EMF. High/Low Trigger Jumpers: The board has a separate jumper for each channel, allowing you to easily select between high and low trigger levels. LED Indicators: A red LED indicates power availability, and separate LEDs for each channel confirm the switch's activation status. Pinout: Control Input: DC+: Positive power supply (+5V). DC-: Negative/GND power supply. IN1/IN2: Control signal receiver pins for channels 1 and 2. Output Screw Terminals: NO (Normally Open): Normally open terminal (current flows only when the relay is activated). COM (Common): Common terminal connected to the load voltage source. NC (Normally Closed): Normally closed terminal (current flows continuously and stops immediately when the relay is activated).
