4kV RS-232 Optical Isolator
232SPHI4
The 232SPHI4 isolates and protects RS-232 equipment from lightning
surges, accidental high voltage shorts, and ground loops. RS-232 data
signals at up to 115.2K bps as well as the RTS and CTS handshake lines
are supported. The 232SPHI4 provides 4000 Volts of isolation between
sides, and maintains creepage and air clearances required for double or
reinforced insulation by IEC 60601-1.
Model 232SPHI4 has 4000 Volts of isolation — twice the rating of most
isolators — to protect RS-232 equipment from lightning strikes, accidental
high voltage shorts and ground loops.
DTE device connections are made through a DB-25 female. DCE device
connections are made through a DB-25 male. The two sides of the isolator
are powered independently to maintain isolation. Both sides can draw
power from the RS-232 data and handshake lines, eliminating external
powering requirements in nearly all systems.
If the isolator is to be used with low power ports or when no handshake
lines are available, external power can be supplied to either side. This
versatile powering configuration minimizes the number of supplies
required by the overall system.
