Signal Isolator SI 99 The
WISCO Signal Isolator is
a WISCO Industries product designed to break the galvanic path between
a transmitted signal source and a receiving device, such as a controller
or recorder. The Signal Isolator solves the problem of transferred signal
distortion due to ground potential differences. The Signal Isolator is
highly effective in eliminating unreliable or inaccurate signal transfer
by providing total current-to-current signal isolation. The Signal Isolator
derives its operating potential from the existing input loop current and,
therefore, does not require a dedicated power supply. The Signal Isolator
is placed in series with the drive signal and provides and output current
that is proportional to the input signal current. |
