8 Channel 12V Relay Module with Optocoupler Isolation

The 8-Channel 12V Relay Module with Optocoupler Isolation is a heavy-duty switching board designed to safely control high-power electrical devices using low-voltage microcontroller signals. Equipped with eight premium 12V relays and dedicated SMD opto-isolators, this module protects your sensitive logic circuits from dangerous voltage spikes and electromagnetic interference. Whether you are engineering a multi-zone smart home setup, an automated industrial system, or driving heavy solenoids, this board ensures reliable operation. If you need to buy online in India to secure your high-voltage switching requirements, this module provides unmatched durability.

This versatile relay board interfaces seamlessly with Arduino, Raspberry Pi, ESP32, and other common 3.3V/5V microcontrollers. It features jumper-selectable high and low-level triggering for each independent channel, offering complete flexibility when designing your circuit diagram and writing your Arduino code. Capable of switching up to 10A at 250VAC per channel, it is the perfect solution for controlling multiple AC appliances and robust mechanical actuators simultaneously.

Features:

• Independent Channels: 8 distinct relay channels, each with an integrated LED status indicator for visual feedback.
• Operating Voltage: Requires a stable 12V DC power supply for reliable coil actuation.
• Optocoupler Isolation: Built-in optical isolation ensures complete electrical separation between logic inputs and high-voltage outputs.
• Adjustable Trigger Mode: Convenient jumper pins allow the selection of either High-Level or Low-Level triggering for every individual channel.
• High Switching Capacity: Comfortably handles heavy loads up to 10A at 250VAC or 10A at 30VDC per relay.
• Robust Connectivity: Features standard heavy-duty screw terminals for secure high-power connections and 0.1" header pins for logic wiring.
