4 Channel Isolated 5V 10A Relay Module opto coupler For Arduino

Experience the next level of control with the 4 Channel Isolated 5V 10A Relay Module with opto coupler, specially designed for compatibility with a wide range of microcontrollers, including Arduino, AVR, PIC, ARM, and more. This versatile module empowers you to effortlessly control various appliances and equipment with a large current.

Equipped with four channels, each relay output can handle a maximum contact of AC250V 10A or DC30V 10A. Connect your microcontroller directly to the standard interface and enjoy the convenience of red working status indicator lights, ensuring safe and reliable operation. The applications are boundless, ranging from MCU control to industrial sectors, PLC control, and even smart home automation.

Switching on your Raspberry Pi has never been easier! This relay module features four 5V relays, each with a rating of 10A/250V. With its opto-isolated digital inputs, you can individually control the on/off state of each relay using a microcontroller output pin. It only requires a voltage of approximately 1.0V to switch the inputs on, while being able to handle input voltages up to 5V. This makes it compatible with a wide range of devices operating between 1.0V and 5V.

Please note that this product may come with one of the following relay types: JQC3F-5VDC-C, SRD-05VDC-SL-C, or FL-3FF-S-Z. Rest assured that regardless of the model you receive, it will meet the highest quality standards.

Benefit from the convenience of high-level and low-level triggered modes. High-level triggering involves short-circuiting the signal input with the VCC cathode, while low-level triggering involves short-circuiting the signal input terminal with the GND negative electrode. This flexibility allows you to adapt the module to your specific needs.

Take advantage of the incredible features offered by this 4 Channel Isolated 5V 10A Relay Module, including a normally closed contact and a normally open contact, triode drive for enhanced relay coil performance, high impedance controller pin, pull-down circuit for malfunction avoidance, power supply and control indicator lamps, and compliance with international safety standards.

Frequently Asked Questions

Can it be controlled from 3.3V boards like ESP32?
Yes, in most cases. The opto-coupler input is active-LOW. For reliable switching, power the relay side (JD-VCC) from 5V and remove the jumper if you want full isolation.

What does the JD-VCC jumper do?
With the jumper fitted, the relays share the logic 5V supply. Remove it and power JD-VCC separately for full electrical isolation.

What loads can it switch?
Each relay is rated 10A at 250V AC or 30V DC — lights, fans, pumps and small appliances. Take proper safety precautions with mains wiring.
