- Enable easy integration with gold design
- Transmit RS485 up to 1.2km
The Waveshare TTL to RS485 (C) Galvanic Isolated Converter, Half-Duplex Communication, Multi-Isolation Protection is a compact device designed to convert TTL signals into differential RS485 signals, supporting half-duplex communication. It is compatible with 3.3V to 5V TTL signal levels and features multiple protection mechanisms, including over-voltage protection and onboard power supply isolation for stable operation.
The converter is equipped with a TVS to suppress surge and transient spike voltages, making it lightningproof and anti-electrostatic. Its design includes a self-recovery fuse and protection diodes to ensure stable current and voltage outputs, enhancing shockproof performance. The immersion gold process and castellated holes facilitate easy integration into various applications.
