Port-powered RS-232 4-channel isolator
The TCC-82 provides full electrical isolation for bi-directional serial
communication between two RS-232 devices in a compact, industrial-
grade package. Both sides of an RS-232 connection are isolated
optically to provide perfect protection against lightning surges,
accidental high voltage shorts, and ground loops. The built-in, wide
range isolators are tested to ensure that they can withstand more than
4 KV rms input to output for 1 minute. This means that the TCC-82 not
only meets the requirements of general serial data communications,
but also the high standards required by industrial automation and
medical applications. The TCC-82 protects the TxD and RxD data
lines, and also protects the RTS and CTS handshake lines for a total
of 4 isolated channels to provide complete protection of your RS-232
applications.

The TCC-82 supports port-powered operation, which means that it
can obtain power directly from the attached serial devices. Power
is obtained from the RS-232 TxD, RTS, or DTR lines, regardless of
whether the signal is high or low, eliminating the need for an external
power supply. However, external power can be used if handshake lines
are not available, if the serial cable is too long, or if the serial device
is a low powered device. For external power, the TCC-82 can use a 5
to 12 VDC adaptor or a USB power cord. Note that both sides of the
connection are powered independently, so if necessary, one side can
rely on port power and the other on an external power source.

When installing the TCC-82, we recommend that you connect all
output signals. The TCC-82 obtains power from these signals even
if they are not used by your system. Care should be taken when
choosing the external power supply if your application requires the
full 4 KV of isolation. Most commercial power supplies provide only
1500 VAC isolation between the primary and secondary windings. If
you are using external power for both sides of the TCC-82, make sure
that separate power sources are used, each with sufficient isolation
protection.
