High-Accuracy 4-20 mA Measurement over USB
Built-in isolated power for 4-20 mA transmitters and sensors
Enables simpler wiring, easy installation, and compact design

Permalink of this page:

Overview

USB-506A is an isolated converter that connects to a PC or other device via USB and measures the 4-20 mA current. By isolating the USB side from the 4-20 mA side, stable measurement can be achieved through improved noise immunity and suppression of transient phenomena. In addition, the isolation provides robust protection for connected equipment.

USB-506A includes a built-in isolated power supply for powering 4-20 mA output devices and sensors, and either 24 VDC or 5 VDC can be used.
By using the dedicated application, USB-506 CV-Monitor, real-time display of measured data, scaling values, and graphs is available on a PC.
Dedicated control commands are also provided, enabling 4-20 mA measurement from user applications.

USB-506A

Features

  • 4-20 mA measurement data acquisition via USB
  • Measurement Range: 0-25 mA

  • Enables 4-20 mA current output, auto-step, and auto-sweep operation via the included application
  • Enables 4-20 mA output from user applications using dedicated control commands
  • Controllable from embedded Linux devices
    It operates as a device of the standard CDC-ACM class.
    For Linux distributions with embedded CDC-ACM device drivers, you can use them without installing the drivers.
    We do not support the use of Linux itself.
