The USB-2055-32 is a full-speed USB device with 16 digital input and digital output channels module, and offers features for industrial control and manufacturing test applications, such as factory automation or embedded machine control. The USB-2055-32 offers 16 isolated channels for digital input and 16 isolated channels for digital output. Either sink-type or source-type digital input can be selected via wire connections. All digital input channels are also able to be used as 32-bit counters. The USB-2055-32 supports source-type output with short circuit protection. There are options to enable both power-on and safety values. The USB-2055-32 has 32 LED indicators that can be used to monitor the status of the digital input and digital output channels. 4 kV ESD protection and 3750 VDC intra-module isolation are standard. With the true Plug & Play capability, it needs not opening up your computer chassis to install boards-just plug in the module, then get or set the data. Owing to another USB feature known as "hot-swapping", users do not even need to shut down and restart the system to attach or remove the USB-2055-32.

The USB I/O utility can help users to configure and test USB-2055-32 quickly and easily without programming; In addition, we also provide the friendly API library and demos for users to develop own USB application with various application development tools (VB / C++ / C#.NET / VB.NET). Therefore, the USB-2055 is the perfect way to add control capability to any USB capable computer.
