USB-2055 Application Image The USB-2055 is a full-speed USB device with 8 digital input and digital output channels module. It offers features for industrial control and manufacturing test applications such as factory automation or embedded machine control. The USB-2055 has 8 isolated channels for digital input and 8 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 16-bit counters. The USB-2055 supports source-type output with short circuit protection. There are options to enable both power-on and safety values. The USB-2055 has 16 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. Since it's a true Plug & Play device, opening your computer's chassis is not required. Owing to another USB feature known as "hot-swapping", shutdowns and restarts are not needed for the system to attach or remove the USB-2055.

The USB I/O utility can help users to configure and test USB-2055 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.
