Unipolar / Bipolar Input

For analog input systems, there are two types of inputs: unipolar and bipolar.
Unipolar inputs:Unipolar signals swing from zero to positive full-scale, thus having only a positive polarity. With the single-ended analog input of an ADC, the input ranges from zero-scale (typically ground) to full-scale (typically the reference voltage). For a unipolar ADC with differential inputs, the positive input swings from zero-scale (the negative input) to positive full-scale (with respect to the negative input).. ...read more.

UNO with PC/104 Extension Kit

UNO is an industrial-grade fanless PC-based platform. The robust hardware and versatile communication port design represents a good choice for a wide range of applications. Since the UNO series products are widely used in industrial applications, onboard I/O and special communication interfaces such as Fieldbus (Profibus, DeviceNet, CAN, etc) become requirements. So the possibility for easy expansion and flexibility is very important.....read more.
