The STMicroelectronics Solid state relay is monolithic 8 channel drivers, designed using STMicroelectronics™ VIPower™ technology, and intended to drive any kind of load with one side connected to the ground. The internal LED matrix driver circuitry (4 rows, 2 columns) allows the efficient driving of the 8 LEDs reporting the on/off status of each of the 8 outputs. Fast demagnetization of inductive loads
Overvoltage protection
Loss of GND protection
