This device utilizes magnetic isolation technology, integrating a three-channel isolator, a tri-state differential line driver, and a differential input receiver within a single chip.
The industrial-grade high-reliability isolated RS485 chip SCCK13011/131012 supports half-duplex communication, provides real-time polarity judgment and correction functions, operates at 2Mbps communication rate, supports 256 bus nodes, and features a fail-safe receiver circuit design.
The figure on the right shows the circuit block diagram of the isolated RS-485 interface chip. .
