Digital Isolators:

ISO7240ADWG4 is a digital isolator designed as a complete digital isolation solution for the protection of data and power in digital systems. The device is housed in an industrial-grade package and provides an interface between high-speed digital systems and the conventional industrial I/O. ISO7240ADWG4 offers true galvanic isolation, input protection against transient voltage and surges, and supply voltage rail protection against over-voltage, brownout, and under-voltage conditions.

The ISO7240ADWG4 application field is in industrial applications requiring isolation, such as data communications, process control, industrial PC’s, motor control systems, automated test equipment, and machine control systems. The device is used to ensure the secure transfer of data between different systems that are separated by huge distances and are subject to different types of electrical interference. Additionally, the device can protect the system from any unwanted transients, surges or voltage spikes, and protect the system from power outages and brownouts.

ISO7240ADWG4 works by using a process called galvanic isolation. This process involves the use of transformers and other energy transfer devices that allow for the exchange of power or data signals between two circuits while completely electrically isolating them. This ensures that even if an interference or voltage spike occurs in one of the circuits, it does not affect the other circuit.

The input and output stages of the ISO7240ADWG4 employ galvanic isolation to ensure that the signal, power or data transfer occurs securely. The device also provides a high level of protection from input transients, surges, and voltage spikes. Additionally, the device acts as a power supply fail-safe for the system by monitoring the power supply voltage and cutting off power to the system in the event of under-voltage or over-voltage conditions.

ISO7240ADWG4 is designed with two independent galvanically isolated channels. Each channel has its own power supply, so that only one of the channels is affected in the event of a power supply failure. Additionally, each channel has its own isolation transformer, which ensures that the data transfer is secure from any interference or voltage spikes.

ISO7240ADWG4 is a powerful and reliable digital isolation solution for industrial systems. The device ensures secure data transfer while providing robust power supply protection and transient voltage and surge protection. It uses galvanic isolation to ensure reliable and secure power and data transfer even across great distances, and its two independent channels provide greater reliability in the event of a power supply failure.
