The ICP DAS USB-2055 provides an easy USB plug-and-play operation with accurate measurement for all kinds of industrial automation applications. Compared with the traditional PC-based card like PCI, and ISA cards, users can achieve data acquisition easier and quicker via USB-2055 I/O module.

The ICP DAS USB-2055 is a full-speed USB device that is equipped with 8 isolated digital input (Dry, Wet) and 8 isolated digital output (Sink, NPN) channels. Either sink-type or source-type digital input can be selected via wire connections which offer features for industrial control and manufacturing test applications such as factory automation or embedded machine control. The USB-2055 supports source-type output with short circuit protection. All input channels not only feature photo-couple isolation, but can also be used as 16-bit counters. The 16 LED indicators can be used to monitor the status of the digital input and output channels.

Users can configure and test USB-2055 directly and easily without any coding via the ICP DAS USB I/O utility. A user-friendly API library is available for users to quickly develop their (VB/C++/C#.NET/VB.NET) applications.
