TTL to RS485 Waveshare Galvanic Isolated Converter

TTL to RS485 Waveshare Galvanic Isolated Converter offers a robust and reliable solution for serial communication in demanding industrial and commercial applications. With its galvanic isolation, lightning protection, surge suppression, and multi-isolation protection features, this converter ensures stable and secure data transmission over long distances, making it an essential component in systems requiring dependable communication in challenging environments.

Features of TTL to RS485 Waveshare Galvanic Isolated Converter:

• Compatible with TTL/RS422 standard, converting the TTL signal into a balanced differential RS485 signal, supporting half-duplex communication
• Compatible with 3.3V ~ 5V TTL signal level, with anti-reverse connection and anti-over-voltage circuit on the power supply side
• Onboard unibody power supply isolation, provides stable isolated voltage and needs 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, and anti-electrostatic
• Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
• On-board RS485 input and output 120R resistors with built-in jumper caps for switching enable
• Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
