TDFA6032A is an analog output unit that outputs a 0-20mA or 4-20mA current signal from the USB port. Output current can be controlled in 2,048 steps using Windows/Linux compatible control commands.
Features
- Operates on bus power, making it suitable for use with single-board computers like the Raspberry Pi.
- Incorporates a step-up power supply from USB to 24V, enabling the connection of loads up to 750Ω in the current loop with a 24V output.
- The USB/PC side and the current loop side are electrically isolated, preventing noise interference and limiting the impact of accidents.
- Provides free control commands that work on Windows/Linux, facilitating easy integration into custom applications.
- Ideal for developing custom current output devices, testing current signal loops, and emulating 4-wire sensors.
- Offers the reliability of domestic design and support. Bulk orders of 1,000 units are possible.
How to Use
The TDFA6032A is controlled using the "TD-USB".
(To set the current value. The set current is 20mA * setting value / 2,048.)
% td-usb tdfa6032 set 1024
(To get the current value.)
% td-usb tdfa6032 get
1024
(To set the initial value at power-on.)
% td-usb tdfa6032 set INITIAL_DAC_VALUE=300
% td-usb tdfa6032 save
To integrate with custom applications, call TD-USB as an external command. It can be utilized from Python, shell scripts, C#, and more. Please refer to the integration examples in the TD-USB documentation.
