RS232 isolator, 4 kV

Data and control lines galvanically isolated

The Isolator in the compact dongle housing provides galvanic isolation between two RS232 devices with an isolation voltage of 4kV DC and also supports another four handshake signals in addition to the data lines.

Elimination of interference:

The use of isolators in data lines eliminates the effects of interference to which the PC is otherwise subjected through its data cables (ground loops, antenna effects, potential differences), remote lightning strikes).

Electrical isolators are not to be confused with surge protectors that are often incorrectly marketed for the same purpose: Surge protectors have no effect on equalizing currents that exist between the connected devices due to the potential differences, and they cannot prevent damage to interface components by such currents.
