2 Channel 24V Relay Module with Optocoupler | Dual Relay Board 10A 250VAC for PLC, Arduino & Industrial Automation

2 Channel 24V Relay Module with Optocoupler | Dual Relay Board 10A 250VAC for PLC, Arduino & Industrial Automation 

The 2 Channel 24V Relay Module with Optocoupler is a high-quality relay switching board used to control AC and DC appliances safely using a 24V control signal. The module includes two independent relays with optocoupler isolation, which protects the control circuit from electrical noise and high-voltage damage.

Each relay supports switching up to 250V AC or 30V DC at 10A, making it suitable for motors, pumps, lights, heaters, solenoids, and industrial equipment. The onboard optocoupler isolation circuit improves stability and prevents interference, making the module ideal for PLC systems, microcontrollers, and automation panels.
