galvanic isolation

Galvanic isolation is also used for safety, preventing accidental current from reaching ground through a person's body.

Sometimes an alternative type of barrier known as a galvanic isolation barrier may be used.

Galvanic isolation is used where two or more electric circuits must communicate, but their grounds may be at different potentials.

Galvanic isolation ensures data transfer without an electrical connection or leakage path that might create a safety hazard.

However, to avoid ground loops and electrically isolate the slave, complete galvanic isolation by opto-couplers is needed.

The primary and secondary windings of two transformers are not connected to each other (but autotransformers do not provide galvanic isolation).

The SL4 has built in galvanic isolation between USB and audio, with turn on/off muting.

These adapters provide no voltage protection or galvanic isolation, but they maintain TTL support with Minolta film cameras.

Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no metallic conduction path is permitted.

Any switched-mode power supply that gets its power from an AC power line (i.e. off-line converters) requires a transformer for galvanic isolation.

Since, normally, the circuit is connected directly to the network without galvanic isolation, we need a switch in any type of protection circuit used for this kind of LED light.

The flyback converter is used in both AC/DC and DC/DC conversion with galvanic isolation between the input and any outputs.

Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected.

The forward converter is a DC/DC converter that uses a transformer to increase or decrease the output voltage (depending on the transformer ratio) and provide galvanic isolation for the load.

Any devices that provide galvanic isolation or buffering on the DMX line (such as DMX splitters) have traditionally been designed to allow transmission in one direction: from the controller to the devices.

This is due to the lack of galvanic isolation between the DC and AC circuits could allow the passage of dangerous DC faults to be transmitted to the AC side.

If voltage conversion is desired, a transformer will usually be included in either the ac input or output circuitry and this transformer may also provide galvanic isolation between the input and output ac circuits.

If no TTL support, but voltage protection and galvanic isolation is required, the Sony FA-HS1AM can be used instead to mount ISO-based equipment on Auto-lock Accessory Shoe cameras.

In this respect the balanced serial connections USB, RS-422 and RS-485 are better, and Ethernet over twisted pair connections are better yet, because of the galvanic isolation provided by the signal transformers.

For that purpose, it is equipped with vibration resistant connectors, a wide temperature range (for example, silicone insulated leads are used), galvanic isolation of the PC interface and support for typical sensors such as ratiometric pressure sensors, thermocouples and a flow meter.

To use JTAG, a host is connected to the target's JTAG signals (TMS, TCK, TDI, TDO, etc.) through some kind of JTAG adapter, which may need to handle issues like level shifting and galvanic isolation.

When not integrated into a development board, it involves a short cable to attach to a JTAG connector on the target board; a connection to the debugging host, such as a USB, PCI, or Ethernet link; and enough electronics to adapt the two communications domains (and sometimes provide galvanic isolation).
