Moxa | Port-powered RS-232 to RS-422/485 converter. 15 kV serial ESD protection.

<p>The Moxa TCC-80 is a compact and intelligent media converter that provides seamless signal conversion between RS-232 and RS-422/485 standards. Engineered for efficiency and convenience, the TCC-80 is port-powered, drawing its energy directly from the RS-232 TxD, RTS, and DTR lines. This eliminates the need for an external power supply in most applications, simplifying installation and reducing clutter in industrial environments.</p><br><br> <p>This versatile converter supports both half-duplex 2-wire RS-485 and full-duplex 4-wire RS-422/485, ensuring compatibility with a wide range of serial devices. A standout feature is the integrated Automatic Data Direction Control (ADDC) for RS-485 communication. This technology intelligently manages the data flow without requiring any software programming, which streamlines the setup process and ensures reliable data transmission.</p><br><br> <p>While the port-powered design is highly convenient, the TCC-80 also offers the flexibility of using an external power source. For applications involving long serial cables or low-power RS-232 devices, a 5 to 12VDC power supply can be connected via the included USB power cord or a separate adapter. This dual-power capability guarantees stable operation across various installation scenarios.</p><br><br> <p>To further simplify integration, the TCC-80 includes features like automatic baudrate detection and built-in 120-ohm termination resistors. Housed in a compact, IP30-rated enclosure, this robust converter is built to perform reliably in demanding industrial settings, making it the ideal choice for connecting legacy serial equipment to modern communication networks.</p> <h3>FEATURES</h3> <ul> <li>Port-powered from RS-232 handshake lines (TxD, RTS, DTR)</li> <li>External 5-12VDC power input supported for added flexibility</li> <li>Compact, space-saving design</li> <li>Converts RS-232 to RS-422, 2-wire RS-485, and 4-wire RS-485</li> <li>Automatic Data Direction Control (ADDC) for RS-485</li> <li>Automatic baudrate detection up to 115.2kbps</li> <li>Built-in 120-ohm termination resistors</li> <li>LED indicator for easy power status monitoring</li> </ul> <h3>SPECIFICATIONS</h3> <ul> <li><strong>Serial Standards:</strong> RS-232, RS-422, RS-485</li> <li><strong>RS-232 Connector:</strong> DB9 Female</li> <li><strong>RS-422/485 Connector:</strong> Terminal Block</li> <li><strong>Baudrate:</strong> 300bps to 115.2kbps</li> <li><strong>RS-485 Data Direction Control:</strong> ADDC (Automatic Data Direction Control)</li> <li><strong>Input Voltage:</strong> 5 to 12VDC (External Power)</li> <li><strong>Input Current:</strong> 30mA @ 5 to 12VDC</li> <li><strong>Housing:</strong> Plastic top cover, metal bottom plate</li> <li><strong>IP Rating:</strong> IP30</li> <li><strong>Dimensions:</strong> 42 x 80 x 22mm</li> <li><strong>Weight:</strong> 50g</li> <li><strong>Operating Temperature:</strong> 0 to 60°C</li> <li><strong>Storage Temperature:</strong> -20 to 75°C</li> <li><strong>Ambient Relative Humidity:</strong> 5 to 95% (non-condensing)</li> </ul> <h3>WARRANTY</h3> <p>5-Year Limited Warranty</p>
