Network isulators must be used wherever electrically conductive connections via network cables are not permitted. This can be in commercial as well as in public and private areas. The usual areas of application are:
In medicine: Network isolators protect patients and medical devices from excessive leakage currents that can flow over the data network. Every device connected to the network represents a risk. With the connection to the data network, this also becomes a risk for the patient. A network isolator is also always required for systems that establish a connection between the patient and outside the patient area. Network isolators protect patients, equipment and users from dangerous leakage currents that can occur unpredictably at any time.
Measuring and monitoring equipment: Network isolators protect sensitive measuring and monitoring equipment in electrical test fields, which are connected to a control center via Ethernet interfaces, from interference voltages and potential differences.
Server systems: To avoid failures or potential equalization currents, network insulators protect server systems that are connected over long distances using copper cabling.
Audio applications: Network insulators provide reliable protection against overvoltages and low-frequency alternating voltages (network hum), thus improving sound quality.
