TD301M485

The primary function is to convert logic levels to RS-485 differential levels and achieve signal isolation. This is an RS-485 transceiver module based on IC integration technology, integrating power isolation, signal isolation, RS-485 communication, and bus protection in a single package. The product features a built-in regulated isolated power supply, providing 2500VDC electrical isolation. It supports automatic transmit/receive switching, eliminating the need for manual control via TX/RX control pins, which reduces design complexity. The product can be easily embedded into user equipment, enabling seamless RS-485 network connectivity.
