by ICP DAS

4/8-channel Digital Input Counter / Frequency / Encoder Module USB 2.0 Full-Speed and USB Bus powered. Plug-and-Play without drive. Lockable USB cable with temperatures between -25° C ~ 75°C (-13°F ~ 167°F) (RoHS).

Description
Specification
Datasheet

The USB-2084 is a full-speed USB device with 8-channel for Frequency and Up Counters, or 4-channel for Up/Down, Dir/Pulse and A/B Phase Counters. It offers features for industrial control and manufacturing test applications, such as factory automation or embedded machine control. Plug & Play capability, eliminates the need to open up the computer chassis and allows for "hot-swapping". Shut down and restarting system to attach or remove a peripheral is not needed.

The USB I/O utility can help users to configure and test USB-2084 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-2084 is the perfect way to add measurement and control capabilities to any USB capable computer.
