Analog inputs

8.2.1 Overview

With the A/D conversion board APCI-3003 you can achieve high operational
capacities with simultaneous conversion of 4 channels.
The board has 4 differential inputs. Each channel has its own A/D converter.
All 4 analog modules are always started synchronously, only the parameterized
channels will be written fort he user into an especially designed read register
(FIFO, AUTOREFRESHRAM).
The analog acquisition also can be triggerd through a digital input (see chapter
8.2.4 input modes).

8.2.2 Voltage ranges

The analog input ranges (0..10V, ± 10V, 0..5V, ± 5V, 0..2V, ± 2V, 0..1V, ± 1V, 0-
20 mA) and the gain can be configured through the software.
This enables different voltages (or rather currents) from channel to channel and
the A/D converter's best resolution.
