Module USB 16 kênh DI + 16 kênh DO ICP DAS USB-2255-32 CR
The USB-2255-32 and USB-2255-64 is USB 2.0 I/O devices with 16/32 digital inputs and 16/32 digital outputs. All digital inputs can operate as 32-bit counters and support selectable sink or source configurations via wires. The models also have LED indicators to display the status of the digital channels.
A dual watchdog function with configurable power-on and safe values ensures reliable operation in harsh environments.
We also provide API library and demos with source code for Windows and Linux users to develop their own USB applications with various development tools (VB/C++/C#.NET/VB.NET/LabVIEW). Therefore, the USB-2255-32 is the perfect choose for you to implement I/O expansion via a plug-and-play USB interface.
Built-In USB Hub with Support for Daisy Chaining
The USB-2200 module is equipped with a USB hub that supports daisy chain topologies.
This feature frees up the PC USB ports by enabling more than one USB-2200 module to be integrated into a single system.
Note：The USB 2.0 port provides only 500mA, external power is required when multiple modules are connected to the same USB port. Please refer to the following figure shown daisy chain application
Note：Support daisy-chain, max. 5 nodes.
Redundant Power
The modules support dual power inputs (+10 to +30 VDC) for enhanced redundancy. If one source becomes inactive or is interrupted, the other immediately takes over to ensure uninterrupted operation in critical environments. The modules can operate as normal with only a single power source. (If not using the USB hub function, the module can be powered via a USB 2.0 port.)
