2. About the Product

This product is an analog input unit supporting USB2.0 to provide the input function of analog signal

from USB port on the computer.

Compact design, (188.0(W)×78.0(D)×30.5(H)mm), features flexibility in installation. The product can

be set on the floor, wall, and inside the console or equipment with the DIN rail.

Windows/Linux device driver is supported with this product.

For AI-1608VIN-USB, 8 channels of 16-bit analog input, and digital input and output (4 channels

respectively) are equipped, and these circuits are isolated from the computer.

As the analog input supports differential input, accurate measurement can be performed even when

potential differences with the signal source occur.

The input range supports ±10V voltage input bipolar.

As for AI-1608AIN-USB, 8 channels of 16-bit analog input, and digital input and output (4 channels

respectively) are equipped, and these circuits are isolated from the computer.

As the analog input supports differential input, accurate measurement can be performed even when

potential differences with the signal source occur.

The input range supports 0-20mA current input.

3. Features

1. AI-1608VIN-USB

 8 channels of analog input (voltage input), and

4 channels of digital input and output respectively are

contained with high accuracy

Analog input (10μsec/ch, 16bit, 8ch), and digital input and output (Input: TTL level 4 channels, Output: Open-collector 4 channels) are

equipped. The analog input supports differential input and the ±10V voltage input bipolar.

2. AI-1608AIN-USB

 8 channels of analog input (current input), and

4 channels of digital input and output respectively are

contained with high accuracy

Analog input (20μsec/ch, 16bit, 8ch), digital input and output (Input: TTL level 4 channels, Output: Open-collector 4 channels) are

equipped. The analog input supports differential input and the 0-20mA current input.

3. Common

 Buffer memory available in FIFO format

This product contains buffer memory (8K data) which can be used in FIFO format. You can perform analog input in the background,

independent of software and the current status of the PC.

 Sampling can be driven by a clock or by various triggers

Sampling can be started and stopped by software and external (timing of control signals input from external) triggers.

The sampling period can be controlled by the internal clock (high-precision timer included in the product).

 Isolated from the bus by a digital isolator

This product isolates the PC from analog input as well as digital I/O by a digital isolator, which improves the noise performance.

 Open collector output for digital output

The use of open collector output ensures digital outputting with TTL or 12-24 V power by the power of the external device.

 Compact design not restricting installation location

(188.0(W)×78.0(D)×30.5(H))

Compact design of 188.0(W) × 78.0(D) × 30.5(H) does not require special installation location.
