Connection Example

The TDFA50607 is a 7-channel USB digital I/O output board. It allows you to output 12/24V signals to various external devices using simple commands. Thanks to electrical isolation, it offers excellent safety and noise immunity.

Features

Supports both 12V and 24V systems.
Operates via USB bus power (Note: USB side only; an external power supply is required for the device side). Compatible with board PCs like Raspberry Pi and Armadillo.
Recognized as a standard USB HID device, so no special driver installation is needed.
Simple control commands are available for both Windows and Linux, making integration into applications easy.
The USB section and output section are electrically isolated, ensuring high safety and noise resistance.
Each channel has a built-in LED, making it easy to check the signal status at a glance.
A single PC can control multiple devices. With a USB hub, you can connect dozens of units.
DIN rail mounting is supported using the optional mounting kit (Model: TDAC-DMK).
Designed and developed in Japan. Mass production, customization, and support are available.

How to Connect

An equivalent circuit diagram of the output section is shown in Photo 2 (only 3 channels shown).
Connect the positive terminal of the external power supply to the Common terminal, and connect the positive input terminals of your target devices to each contact channel.
Each contact uses an emitter-follower transistor output.
When a contact is turned ON via USB, the transistor is activated through a photocoupler.

Control Commands

Control is performed using TD-USB, the standard command-line tool from Tokyo Devices.

→ `3` in binary is `0000011`, meaning Channels 1 and 2 will be turned ON.

For detailed usage, please refer to the TD-USB documentation via the link below.

To integrate with your own application, simply call the TD-USB command from your program.
You can use it from Python, shell scripts, C#, LabVIEW, and more.
Refer to the TD-USB documentation for integration samples.

The demo application TD-AppKit allows you to control each contact via a GUI (Windows only).
