Introduction
Summary
This product is a USB2.0 compatible terminal module that extends the analog input function of USB
port of PCs. This product features 4ch 16-bit analog input and is isolated from the bus line to the PC.
The signal lines can be connected directly to the terminals on this product. To simplify use in
embedded applications, this product includes a bracket for attaching to a 35mm DIN rail. The number
of input channels can be increased by purchasing an optional device module. Windows driver is
bundled with this product.

resolution, differential input 4ch). Compatible to USB1.1/USB2.0 and capable to achieve high speed
transfer at HighSpeed (480 Mbps). Selectable input ranges common to channels: Bipolar input from -10
to +10 V and current input from 0 to 20 mA. The range is set by software and switch.
- Isolated from the bus by a digital isolator
This product is isolated by a digital isolator which improves the noise performance with respect to the
PC.
- Equipped with the buffer memory (256K data) which can be used in either FIFO or ring format
This product includes buffer memory (256K data for analog input) which can be used in either FIFO or
ring format. You can perform analog input in the background, independent of software and the current
status of the PC.
- Windows compatible driver libraries are attached.
Using the attached driver library API-USBP(WDM) makes it possible to create applications of
Windows. In addition, a diagnostic program by which the operations of hardware can be checked is
provided.
- Sampling can be driven by a clock or by various triggers
Sampling can be started and stopped by software and level comparison (compares the level of a
specified channel with a specified compare level value) triggers.
The sampling period can be controlled by the internal clock (high-precision timer included on the
board).
- Easy to increase the input channels using an expansion module
Adding optional modules (up to 3 units) can easily increase the input channels. The unique structure for
connection by stacking enables easy and compact system configuration.
- Capable of being mounted on 35-mm DIN rails
This product is equipped with an attachment for mounting on 35-mm DIN rails on the back, allowing
the module to be attached onto and detached from DIN rails.
