[USB-050V] 2 Channel USB Analog Voltage Monitor
Under Development
Measurement data from 2 analog channels (±10V)
can be acquired via USB.
The USB interface is independently isolated from each channel.
Overview
USB-050V is a voltage monitor capable of measuring two channels of analog voltage (±10 V) via USB. The USB interface and each channel are independently isolated. An A/D converter is provided for each channel, enabling simultaneous measurement of two channels.
Power is supplied from the computer via the USB connection. When using a USB hub or similar device for branching, ensure that a stable power supply is provided to prevent voltage drops. If the voltage is insufficient, stable measurement may not be possible.
By using the included application software, USB-050V Voltage Monitor, measurement results, scaling values, and chart displays can be viewed on a computer.
In addition, by using the dedicated control commands, analog voltage (±10 V) measurements can also be performed from a custom application.

Features
- Measurement data from 2 analog channels (±10 V) can be acquired via USB.
- Measurement Range: ±10 V
- Measurement Accuracy: ≤ ±0.05% FS
- USB side and each channel are electrically isolated (2500 VDC)
- Enables voltage monitoring, scaling, and chart visualization via the supplied software.
- Enables measurement of analog voltage (±10 V) 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. - Easy control via virtual COM port with USB connection to a PC
- No external power supply is required
USB-050V is powered through a USB port (Bus-powered) - ESD and surge protection
- Pluggable the screw terminal
- Housing material: Plastic
- DIN rail, magnet, and screw mountable (Attachment is required)
- Includes a USB cable (1.8 m)
- Free from the 10 RoHS-restricted substances.
- MADE IN JAPAN
