5PCS 1 Channel 24V DC Relay Module Board with Optocoupler

About this item

• 1-Channel Switching Control – Control a separate circuit via a single digital input from one compact relay board, making it a practical relay module for automation builds, test projects, and load control setups.
• 24V Active-Low Trigger Design – Designed for 24V DC control systems with active-low triggering, allowing easy connection to many MCU boards, PLC outputs, and compatible control circuits.
• Optocoupler Interface – Built with onboard optocouplers to help separate the signal side from the relay side, supporting cleaner switching in mixed low-voltage and load-control projects.
• Clear Status Indicators – Each relay channel includes an indicator light, so you can quickly check operating status during wiring, testing, troubleshooting, and project adjustments.
• Rated for Common Control Applications – Relay contacts are rated up to AC 250V 10A or DC 30V 10A, suitable for MCU control, PLC projects, home automation, appliance switching, and other loads within the stated ratings.
