    TTL To RS485 Isolated Converter DIN-Rail

    DIN Rail-Mount TTL To RS485 Galvanic Isolated Converter, 600W Lightningproof & Anti-Surge, Multi-Isolation Protection


    • Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supporting half-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, lightning proof & anti-electrostatic
    • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
    • Onboard RS485 output terminal 120R resistor, enabled/disabled via switch
    • Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective

    Primary Function

    Converting The TTL Signal Into a Balanced Differential RS485 Signal
    For Interface Converting, Expanding Nodes And Long-Distance Communication

    DIN 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 Lightningproof Diodes and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance

    Communication Connection Diagram

    TTL convert to RS485, point to point, half-duplex communication, suitable for interface conversion

    TTL convert to RS485, point-to-multipoint, half-duplex communication, suitable for expanding nodes

    Two groups TTL To RS485 conversion, point-to-point, half-duplex communication, suitable for extending the communication distance of TTL

    Application Examples

    The TTL To RS485 (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 RS485 conversion such as Industrial Automation and IoT.
