Features:
This is a solid state relay that provides a function similar to an electromechanical relay but has long-term reliability.

This 5V solid state relay has 4 channels, each channel 240V 2A.
The relay output has resistive fuse 240V 2A.
Large load capacity, the rated output load is 2A at 100 to240VAC(50/60Hz) for general purpose use.
Designed with screw terminal blocks for convenient wiring.
