Introduction

The TCC-82 provides full electrical isolation for bidirectional 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 one 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 it also protects the RTS and CTS handshake

lines for a total of four isolated channels to provide complete

protection of your RS-232 applications.

External Power Source Not Required

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-power device. For external power, the TCC-82 can

use a 5 to 12 VDC adapter 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.
