Waveshare Rail-Mount TTL to RS232 Galvanic Isolated Converter, Full-Duplex Communication, Lightningproof & Anti-Surge, Multi-Isolation Protection, TTL Serial Converter

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 ^^ 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, lightningproof & anti-electrostatic ^^ Onboard protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance ^^ Onboard 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
