Analog/Contact Input Module
Intrinsically safe ia/ib circuit 1:
Voltage supply U
0
= 4 to 30 V
Current consumption @ 30 V, max. 100 mA
Intrinsically safe ia/ib circuit 2:
Voltage supply U
0
= 4 to 30 V
Current consumption @ 30 V, max. 100 mA
Intrinsically safe ia/ib circuit:
Maximum load 500 W

Parallel connection of the two input circuits (term. 81/82
and 83/84) to supply the contact outputs with power from a
single intrinsically safe circuit is also permissible.
