Description

These modules make up to 20 external analog inputs available. Measurements can be taken from any of these inputs either as a ground-referenced channel or, in combina-tion with another input, as a differential channel. Each channel can be switched by software. Up to a maximum of 20 ground-referenced channels or 10 differential channels are therefore possible. It is also possible to set each channel by software to one of 8 input voltage ranges (from ±10 Volt to ±250 mV). The low-cost X-AD12-16/L module, which only offers two input voltage ranges, is an exception. The va-rious modules differ in the resolution and maximum conversion rates ( 0.4 Msps to 3 Msps).
