Digital inputs/outputs
The 18 digital pins can be configured by software as inputs or outputs in groups of 4 (D0..D3, D4..D7,
D9..D12, D13..D16) or individually (D8 and D17).
Analog inputs
The module provides 4 analog differential inputs with 12 bit resolution. Module Version /U supports
4 ranges (0...5 Volt, 0...10 Volt, +-5 Volt, +-10 Volt).
A gainfactor (1 ... 1000) can be set for each channel by inserting a resistance.
Module version /i has 4 current inputs (0...20 mA).
In addition 4 internal signals can be measured:
5V reference voltage, 3,3V power supply, analog ground and module temperature.
Analog outputs
Module version /U supports 4 different ranges (0...5 Volt, 0...10 Volt, +-5 Volt, +-10 Volt) per
channel.
Module version /i supports current outputs (0...20 mA).
