An improved circuit with an optocoupler type TLP621 is shown in Figure 2. Figure 2 A circuit with an optocoupler (TLP621) which generates higher (even) harmonics that can be added to the original ...

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 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 ...

The example circuit above was built using IRF540N N channel hexfets with 250 ohm gate resistors. The back-to-back configuration of the FET provides linearity in impedance across 0V when the device is ...
