network isolator

Network isolators are used in the medical industry to protect patients against leakage currents.

Networks isolators should be installed as close as possible to the medical device in question.

The network isolator is therefore a passive device, and functions without any requirement of an external power supply.

Network isolators are commercially available in various designs, to suit customers' requirements:

Network isolators work to remove this hazard, by electrically disconnecting medical devices from a network.

A network isolator can be constructed to provide one or both required MOPPs.

Network isolators have many other applications in overcoming the problems of differing ground potentials across networks, or between network components.

Network isolators are installed as part of a copper Ethernet system, as galvanic isolators.

The number of MOPPs a network isolator provides will be stated in the certification of the device.

The transmission quality of a network isolator can be determined by measuring the industry standard parameters or characteristics, for example, insertion loss, return loss, and near end crosstalk.

By definition, a network isolator completely eliminates each and every direct electrical connection between devices connected through a network connection - specifically all the data lines, and the cable shield.

As they serve no therapeutic or diagnostic purpose, network isolators themselves are not classed as medical electronic equipment according to the standard IEC 60601-1, nor do they fall within the scope of the Medical Devices Directive 93/42/EEC.
