КР-485 - Interface conversion block RS-485

Order code:

КР-485

Number:

Available for order.

The KP‑485 interface converter is designed for:

  • 🔄 Bidirectional signal conversion between RS‑485 and USB interfaces;
  • Programming and configuring devices operating via the RS‑485 interface;
  • Temporary or service connections, as it is not recommended for continuous SCADA communication due to the lack of galvanic isolation.

The converter is powered from the USB bus and automatically detects the data transmission direction in RS‑485 half‑duplex mode, making it convenient for industrial device setup and testing.

Main Functions

  • 🔄 Signal conversion RS‑485 ↔ USB;
  • Automatic data direction detection for RS‑485 half‑duplex mode;
  • No galvanic isolation, limiting use to service or temporary applications;
  • 💻 Creation of a virtual COM port, compatible with standard serial communication software;
  • 🔋 Powered via USB, no external power supply required.
