Waveshare Rail-mount TTL To RS485 Galvanic isolated Converter, 600W Lightning proof & Anti-Surge, Multi-Isolation Protection

Waveshare Rail-mount TTL To RS485 Galvanic isolated Converter, 600W Lightning proof & Anti-Surge, Multi-Isolation Protection.TTL TO RS485 (B) is an industrial-grade rail-mounted electrically isolated TTL-to-RS485 serial converter.

Features:

1. Compatible with TTL/RS422 standard, converting the TTL signal into a balanced differential RS422 signal, supporting half-duplex communication
2. Compatible with 3.3V ~ 5V TTL signal level, with anti-reverse connection and anti-over-voltage circuit on the power supply side
3. Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
4. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption
5. Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, and anti-electrostatic
6. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
