Waveshare Rail-mount TTL To RS232 Galvanic isolated Converter, Full-Duplex Communication, Lightningproof & Anti-Surge, TTL Serial Converter
The Waveshare Rail-mount TTL to RS232 Galvanic Isolated Converter offers a robust solution for industrial and harsh environment applications requiring reliable serial communication. This converter seamlessly bridges TTL (Transistor-Transistor Logic) level signals to RS232 levels, enabling full-duplex communication while ensuring galvanic isolation, lightning protection, and surge suppression. Its rail-mount design enhances installation flexibility and reliability in demanding environments.
User Manual / Datasheet / Example Codes Etc.
Features
- Compatible with TTL/RS232 standard, converting the TTL signal into a balanced differential RS232 signal, supporting full-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 with lightning-proof and ESD protection.
- Onboard protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, and improve shock resistance.
- Onboard power supply screw terminal for 3.3V~5V DC input.
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
