New Products
2025-09-12
Introduction：
The USB-2255-32 is USB 2.0 I/O devices with 16 isolated digital inputs and 16 isolated digital outputs. All digital inputs can operate as 32-bit counters and support selectable sink or source configurations via wiring. The models also includes LED indicators that display the status of each digital channels.
A dual watchdog function with configurable power-on and safe values ensures reliable operation in harsh environments.
We also provide an API library and sample programs with source code for Windows and Linux users, supporting various development tools (VB/C++/C#.NET/VB.NET/LabVIEW). Therefore, the USB-2255-32 is an ideal choice for implementing I/O expansion via a plug-and-play USB interface.
