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 5V relays rated at 10A/250V each. It is designed to switch up to 4 high current (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 5V. This makes it ideal for 1.0V to 5V devices.

Specifications and Features:-

• One normally closed contact and one normally open contact
• Channel: 4 channel
• Relay Operating Voltage: 3.3V to 5V
• Triode drive, increasing relay coil
• High impedance controller pin
• Pull-down circuit for avoidance of malfunction
• Power supply indicator and Control indicator lamp
• Power supply and relay instructions, lit, disconnect is off;
• 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 close contact;
• The module is compliant with international safety standards, control and load areas isolation trenches.
