The input voltage range is 18 to 30 volt dc and the input current

source is 6 mA at 24 V. The inputs are divided into two individualy

isolated groups with eight channels and one voltage supervision

input in each group. Every input channel consists of current limiting

components, EMC protection components, input state indication

LED and optical isolation barrier. The process voltage supervision

input give channel error signals if the voltage disappears. 

The error signal can be read through the ModuleBus.

Features and benefits

• 16 channels for 24 V d.c. inputs with current sinking

• 2 isolated groups of 8 with voltage supervision

• Input status indicators
