Features
The USB-2068-18 is a user friendly, 8-channel Form C relay output and 10-channel digital input module with the USB interface. It’s design allows all digital input channels to be used as 32-bit counters and can also be selected as a sink/source type and dry/wet contact via wire connections. The USB-2068-18 can also configure power-on and safe values. The USB-2068-18 is equipped with 8 kV ESD protection(for all channels) and 3750 VDC intra-module isolation(for digital input channels) to enhance noise protection capabilities in industrial environments.
The USB I/O utility can help users to configure and control USB-2068-18 quickly and easily, no programming required. An API library and demos for users developing their own USB application with various application development tools (VB/C++/C#.NET/VB.NET) are provided. The USB-2068-18 is the perfect way to add control capability to any USB capable computer.
