Product Description

 

OC03 is a low-voltage control relay module able to switch AC and DC loads.

The optically isolated relay is controlled by a PCA9554A IO expander, which provides an control interface to the switch. The PCA9554A has several selectable I2C addresses accessible via solder pads.

The TLP241A photorelay consist of a photo MOSFET optically coupled to an infrared light emitting diode which switches a AC or DC load. It provides an isolation voltage of 5000 Vrms, making it suitable for applications that require reinforced circuit insulation.
