The Waveshare TTL To RS485 (C) Galvanic Isolated Converter converts the TTL signal into a balanced differential RS485 signal, which can be used for interface conversion and node expansion, and can also be used to extend the communication distance.
Features:
- Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supports half-duplex communication.
- Compatible with 3.3V ~ 5V TTL signal level, provides over-voltage protection for power supply interface.
- 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, low power consumption.
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic.
- Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, improve shockproof performance.
- Onboard RS485 output terminal 120R resistor, enabled via soldering.
- Black immersion gold process design, compact size, easy to integrate.
