Function description
The electronic module PSSu E AI SHT2 contains two shunts for scaling an input current I
I0
(connection I0). The two current outputs I
O0
(connection O0+) and I
O1
(connection O1+) are
evaluated by analogue current inputs.
Scaling is applied during evaluation via an analogue input module with an input resistance
of 115 Ohm, (e.g. PSSu E F AI I)
