Network Isolators

EMOSAFE Network Isolators are used in copper-based network connections in private, public, and commercial sectors.
They protect connected equipment against extraneous voltage sources and overvoltage, which can arise from installation errors, aging components, or moisture at the network interface. They attenuate low-frequency signal components and thus protect connected equipment from ground loops and other problems. Overvoltages induced by lightning strike and switching processes can be inductively coupled into network lines. Such overvoltages can be restrained by Network Isolators.

EMOSAFE Network Isolators are primarily used in medical applications. They conform to the high requirements which IEC 60601-1 places upon galvanic isolation devices in the medical field.

Further information on EMOSAFE Network Isolators:

All EMOSAFE Network Isolators have a dielectric strength of at least 4 kV AC, and comply with the requirements of IEC 60601-1.

Technology

EMOSAFE Network Isolators operate based on the principle of electromagnetic induction. Because of this transmission principle, Network Isolators do not require separate power supplies. There are no software drivers to be installed. Transmitter modules developed especially for our Network Isolators reach dielectric strengths of up to 6000 V AC and 8500 V DC (model dependent); and with a three-layer insulation system, conform to the highest safety requirements. At the same time they facilitate a particularly low-loss signal transfer, so that the usual maximum Ethernet network path length of 100 meters can be fully utilised in most cases without leading to a reduction in data throughput.

Further questions regarding the technology and the operation of Network Isolators are answered on our FAQ-Site.
Detailed information on individual products can be found in the product-related documents within the Network Isolators section.

Scopes of Application

  • Medical electrical devices whose operation is permitted only when existing signal interfaces present a standards-compliant means of separation. Hence the frequently used term “medical network isolator”.
  • Sensitive measuring and monitoring devices in electrical testing laboratories, which are connected through an Ethernet network to a control centre, and need to be protected from transients and potential differences.
  • Computer systems which are electrically connected over long distances via Ethernet cabling, where potential equalising currents need to be prevented.
  • Audio applications, to reduce the transmission of low frequency alternating currents (AC hum) over the network connection.
  • Applications where valuable or especially vulnerable devices need to be protected from overvoltage and line noise from peripheral network equipment.

Quality

The development and production of our network isolators is certified according to ISO 9001:2008 and DIN EN ISO 13485.
Before delivery EMOSAFE network isolators are subjected to an individual check, in which the electric strength of every single product is tested and documented.
To be able to ensure optimal transmission quality the EMOSAFE network isolators are also tested for observance of our high quality requirements with regard to the important characteristic values for the transmission properties, insertion loss, return loss and local crosstalk.
