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

Rail-Mount TTL To RS422 (B)

Galvanic isolated Serial Port Converter

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 resistance
• 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

Specifications

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 resistance

Interface Introduction

* 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.

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.
