    Industrial 2-Ch Cache-type RS485 Hub, Wide Baud Rate Range, 2 master and 1 slave / 1 master and 2 slaves

    $30.99

    • Dual Operation Modes: Functions reliably as a 2-master-1-slave or 1-master-2-slave RS485 distributor, solving multi-host communication conflicts.

    • Independent Port Configuration: Each of the three RS485 ports supports individual baud rate settings (1200-460800bps), offering flexible serial communication management.

    • Advanced Data Filtering: Utilizes whitelist and address mask for precise data selection, enhancing network control.

    • Clear LED Diagnostics: Equipped with dedicated LED indicators for each port’s transmit and receive status, enabling instant visual monitoring.

    • Rugged Industrial Design: Features DIN rail mountable housing with 9-24V wide-range power input, built to industrial-grade standards.

    • Network Expansion: Effectively acts as an RS485 system expander or RS485 multiport hub, allowing flexible device connectivity.
