ADA16-32/2(PCI)F

1. Setting the Conversion Conditions

First, set the conditions for executing analog input.

Resolution

”Resolution” signifies the number of bits used by an analog input device to represent analog signals.

The higher the resolution, the more finely the voltage range is segmented, allowing the device to

convert analog values to digital equivalents more precisely.

A device with a resolution of 12-bit divides the range width into 4096 segments.

When the device covers the range of 0 - 10V, the minimum unit of converted voltages is 10÷4096

≈

2.44mV.

If the device has a resolution of 16-bit, it is 10÷65536

≈

0.153mV instead.

ADA16-32/2(PCI)F

: The resolution is 16-bit.

Input Mode

”Input Mode” indicates the method of connecting analog input signals.

The input modes available are single-ended input and differential input.

The single-ended input mode is suitable for the environment in which the potential difference between

the signal source and ground and noise components can be ignored. For the environment in which they

cannot be ignored, the differential input mode is suitable.

The number of channels available in differential input mode is half that in single-ended input mode.

This board uses on-board jumpers to set the input mode.

Channel

”Channel” represents each point of analog input.

For individual channel numbers, see “Using the On-board Connectors” to “Connector Pin Assignment” in

Chapter 3 "External Connection".

You can specify an arbitrary number of points of analog input by setting the channels by means of

software.
