Waveshare Rail-Mount TTL To RS422 Isolated Converter, Anti-Surge, Multiple Isolation Protection

Compatible with TTL/RS422 standard, converting the TTL signal into differential RS422 signal, support 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, and low power consumption ^^ Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-electrostatic. Onboard RS422 input and output terminal 120R resistor, enabled/disabled via jumper ^^ Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance ^^ Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
