The Waveshare Rail-mount TTL to RS485 Converter is an industrial-grade communication module designed to convert TTL (UART) level signals to RS485 differential signals with multi-layer isolation protection. Featuring galvanic isolation for both power and signal lines, it ensures safe and reliable data transmission in environments prone to electrical noise or ground loops. This module is specially designed for DIN rail mounting, making it ideal for industrial automation, monitoring systems, PLC communication, and remote serial device interfacing.
It supports multi-point communication, allowing multiple RS485 devices to be connected to a single bus. The built-in TVS (Transient Voltage Suppression) diode and isolation transformers offer enhanced protection against ESD, surge, and electromagnetic interference.
Key Features:
• Galvanically isolated power and signal paths for robust protection
• Converts TTL/CMOS UART signals to RS485 differential signals
• DIN rail mountable for industrial environments
• Supports multi-device communication on RS485 bus
• Built-in TVS protection, optocoupler isolation, and isolation transformer
• Low-power design with reliable signal transmission
• Compatible with 3.3V and 5V TTL UART signals
