The XTA-120V-6 optocoupler modules have six individually isolated 120-volt AC-DC digital (discrete) inputs to sense on-off levels and provide 5-32V DC logic outputs to a fieldbus input module or a ...

1. The well-established relay-driving circuit uses an optocoupler to isolate the grounds and noise coupling between the low-voltage digital-control signal circuit (left) and the relay as load (right).

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Murrelektronik optocouplers (from $16.50) are used to combine different signal levels or to isolate one signal from another. Optocouplers are similar to relay interfaces, providing an optoelectronic ...
