Waveshare TTL To RS485 (C) Galvanic Isolated Converter
The Waveshare TTL To RS485 (C) is an industrial-grade, galvanically isolated converter designed for reliable serial communication in demanding environments. This module provides bidirectional conversion between TTL and RS485 signals while maintaining high-speed data transmission and robust circuit protection. With built-in power and signal isolation, it effectively prevents ground loop interference and protects sensitive equipment from high-voltage surges.
Product Features
- Onboard unibody power supply isolation provides stable isolated voltage and requires no extra power supply for the isolated terminal.
- Onboard unibody digital isolation allows signal isolation, high reliability, strong anti-interference, and low power consumption.
- Onboard TVS (Transient Voltage Suppressor) effectively suppresses surge voltage and transient spike voltage in the circuit.
- Onboard resettable fuse and protection diodes ensure current and voltage stability, providing over-current and over-voltage protection.
- Integrated lightning protection and ESD protection for the RS485 interface.
- Features a professional-grade plastic case for easy installation and safety.
- RS485 transceiver automatically switches between transmit and receive modes for seamless data flow.
