TCC-82 Serial Port Powered RS-232 4-channel Optical Isolator
  • Dual self-powered or selectable external power source
  • 4-channel 4 KV RMS Isolation for 1 minute
  • Surge protection, 15 KV ESD

TCC-82 is a signal isolator that provides bi-directional serial communication with full electrical isolation between two RS-232 devices. This compact sized isolator isolates both sides of the connection optically to provide perfect protection from lightning surges, accidental high voltage shorts, and most of all, ground loops. The built-in, wide range optocouplers are tested to ensure that they can withstand more than 4 KV rms input to output for 1 minute. This means that TCC-82 not only meets the requirements of general serial data communications, but also the high standards required by industrial automation and medical applications. In addition to the TxD and RxD data lines, TCC-82 also protects the RTS/CTS handshake lines on its two D-type connectors.

Independent RS-232 Serial Port Power

TCC-82 has two power inputs, which means that both sides of the isolator must be powered independently and separately to maintain the isolation. Ideally, both sides can derive power directly from the RS-232 TxD data lines and the RTS/DTR handshake lines, regardless of whether the signal is high or low. This also eliminates the requirements of using external power supplies in most systems. The configuration of the wires and the entire system can be maintained easily. If the applications and devices on one or both sides do not have handshake lines available, the serial cable is too long, or low powered serial ports have been used as the power source, then external USB power cords or 5 to 12 VDC adapters can be used as an alternative.

When connecting TCC-82, it is recommended that all signals that are outputs be connected. TCC-82 derives power from these signals, even if they are not used by your system. Care should be taken when choosing the external power supply if TCC-82's full 4 KV of isolation is required to operate correctly. Most of the commercial power supplies that are available on the market only provide 1500 VAC isolation between the primary and secondary windings. If both sides of the isolator require external power, two separate isolated supplies are required.
