Isolated RS485-TTL Converter Module

The RS485 to TTL isolated converter module from Waveshare is a reliable and compact module that is specially designed to convert TTL signals into differential RS485 signals. With its galvanic isolation, it offers high protection against interference and voltage spikes. The module supports half-duplex communication and is suitable for both point-to-point and point-to-multipoint connections. Thanks to the integrated overvoltage protection functions and robust construction, it is ideal for use in harsh environments. The compact size and immersion gold design facilitate integration into various applications.


Features:

  • The module is compatible with TTL and RS485 standards and converts TTL signals into differential RS485 signals, enabling reliable half-duplex communication.
  • It supports TTL signal levels from 3.3V to 5V and provides overvoltage protection for the power supply interface.
  • The module has a unified power supply isolation, which provides a stable isolated voltage and does not require an additional power supply for the isolated port.
  • On-board digital isolation enables signal separation, high reliability, strong interference resistance and low power consumption.
  • TVS (Transient Voltage Suppressor) effectively suppresses overvoltages and voltage spikes in the circuit, making it lightning and electrostatically safe.
  • Self-recovering fuse and protection diodes ensure stable current/voltage outputs, provide overcurrent/overvoltage protection and improve impact resistance.
  • The RS485 output terminal has a 120R resistance which can be activated by soldering.

Application Examples:

  • Use in industrial automation systems for communication between different devices.
  • Use in security systems to ensure stable and interference-free communication connections.
  • Integration into remote monitoring and control systems to extend the communication range.
  • Use in sensor networks for data transmission over long distances.
  • Use in home automation systems to connect control devices and sensors.
