Waveshare Rail-mount TTL To RS422 Galvanic isolated Converter

Waveshare TTL TO RS422 (B) is an industrial-grade rail-mounted electrically isolated TTL-to-RS485 serial converter.

Features:

• Compatible with TTL/RS485 standard, converting the TTL signal into a balanced differential RS485 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 is anti-electrostatic.
• Onboard resettable fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, and improve shock resistance.
• On-board RS485 input and output 120R resistors with built-in jumper caps for switching enable.
• Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
