The electronic module PSSu E AI SHT1 contains two shunts for scaling
an input current I
I0
(connection I0). The two current outputs I
O0
(connec-
tion 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)
 Scaling factor with resistance R
1
+ R
2
= 1.163 Ohm (connections
O0+/O0-):

Example:
 Input current I

= 500 mA
 Output current I

= 5 mA
 Output current I
