Dimensions

The TDFA60220 is a USB current meter designed for recording and processing 4-20mA analog current signals. It can capture current values in real-time on a PC with a resolution of 12 bits (4,096 levels).

Features

The device reacts quickly to sudden changes in current with a sampling rate of 1,000 samples per second.
Operates on bus power, making it usable with single-board computers like Raspberry Pi.
The USB/PC side and the current loop side are electrically isolated, preventing noise interference and limiting the impact of accidents.
Control commands that work with Windows/Linux are provided, making it easy to integrate into custom applications.
Calibration is possible through control commands.

Quick Start

TDFA60220 is control by "TD-USB", the standard command of TokyoDevices.

(Acquire the current value once. Unit: mA)
% td-usb tdfa60220 get
3.42311

(Continuously acquire values. 1,000sps)
% td-usb tdfa60220 listen --loop
3.42311
3.5392
3.5392
...

(Record data in a text file.)
% td-usb tdfa60220 listen --loop > current.txt

To integrate with a custom application, call TD-USB as an external command. It can be used from Python, shell scripts, C#, etc. Please refer to the integration examples in the TD-USB documentation.
