This converter converts TTL signals to RS232 signals, supporting full-duplex communication. It is compatible with TTL/RS232 standards and can handle TTL signal levels ranging from 3.3V to 5V. It has built-in anti-reverse and over-voltage protection for the power supply interface, providing safe and stable work on your next project.
The unibody power supply isolation provides a stable isolated voltage, eliminating the need for an additional power supply for the isolated terminal. Additionally, the unibody digital isolation improves signal isolation, providing high reliability and strong anti-interference capabilities. The device is designed for low power consumption, making it an efficient solution for a variety of communication projects.
Features
- Compatible with TTL/RS232 standard, converting the TTL signal into RS232 signal, supports full-duplex communication
- Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and over-voltage protection for power supply interface
- Unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
- Protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, improve shockproof performance
- Power supply screw terminal, allows 3.3V~5V DC input
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
