Galvanic isolated Serial Port Converter
- 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, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
- Onboard RS422 input and output terminal 120R resistor, enabled/disabled via jumper
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective

* Note: the TTL TO RS422 (B) is designed to be used with RS422 devices, however, it is also possible to be used with RS485 devices (yet only sending is available). It is recommended to use TTL TO RS485 (B) for RS485 device.
TTL convert to RS422, point to point, full duplex communication, suitable for interface conversion
TTL convert to RS422, point-to-multipoint, full duplex communication, suitable for expanding nodes
Two groups TTL to RS422 conversion, point-to-point, full duplex communication, suitable for extending the communication distance of TTL
The TTL TO RS422 (B) can be widely used for point-to-point, point-to-multipoint, long distance cascaded communication network between two hosts, or between host and MCU/Peripheral. It also can be used in the application scenarios that require TTL to RS422 conversion such as Industrial Automation and IoT.
