4 Channel 24V Relay Module with Optocoupler Isolation

The 4-Channel 24V Relay Module with Optocoupler Isolation is an industrial-grade switching board designed to safely control high-power devices using low-voltage logic signals. Equipped with premium 24V relays and dedicated SMD opto-isolators, this module completely protects your sensitive control circuits from dangerous voltage spikes and electromagnetic interference. Whether you are engineering a custom automated hardware system, wiring a PLC panel, or driving heavy mechanical solenoids, this board ensures highly reliable operation. If you need to buy online in India for your high-voltage switching requirements, this robust module is an ideal solution.

This versatile relay board is fully compatible with standard 3.3V and 5V logic microcontrollers, making it easy to integrate into your existing setups. It features jumper-selectable high and low-level triggering for each independent channel, offering immense flexibility when designing your circuit diagram and writing your automation code. Capable of switching up to 10A at 250VAC per channel, it is an essential component for controlling AC appliances, high-torque DC motors, and industrial actuators.

Features:

• Independent Channels: 4 distinct relay channels, each featuring a dedicated LED status indicator for quick visual diagnostics.
• Operating Voltage: Requires a stable 24V DC power supply for reliable relay coil actuation, perfect for industrial control cabinets.
• Optocoupler Isolation: Built-in optical isolators provide complete electrical separation between the logic inputs and high-voltage outputs.
• Adjustable Trigger Modes: Convenient jumper pins allow the selection of either High-Level or Low-Level triggering for each individual relay.
• High Switching Capacity: Each relay can comfortably handle heavy loads up to 10A at 250VAC or 10A at 30VDC.
• Robust Connectivity: Uses standard heavy-duty screw terminals for secure high-power connections and 0.1" header pins for simple logic interfacing.
