Features at a glance
- 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

Primary function
Converting the TTL signal into balanced differential RS422 signal
for interface converting, expanding nodes and long-distance communication
Rail-Mount Support
Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely
Multiple Protection, Safe And Stable
Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, anti-electrostatic. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock proof performance.

- 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
Application Examples
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.
