Here are a few more instructions regarding the input configuration:
1. Process signals (Proc) and strain gage (DMS) sensors (LoAd)
When connecting process signals or strain gage (DMS) sensors the input signal range
must be specified.
Process signals: There are 2 voltage ranges (0-1 V, 0-10 V) and 2 current ranges
(0 - 1 mA, 0 - 20 mA).
If you have selected "
VOLT
", 2 input ranges are offered.
Select between: "
1V
" for inputs 0 - 1,
"
10V
" for process signals 0 - 10V.
The maximum voltage amounts to 10 V.
However, if you have selected
"AMP" , you have the following ranges at
your disposal: "
1mA
" for the input 0 - 1 mA,
"
20mA
" for the inputs 0 - 5 mA,
0 - 20 mA or 4 - 20 mA.
The maximum current amounts to 20 mA.
Strain gage sensors: If the device is to be used as a DMS strain gage indicator, select one of
the following input ranges:
"
15 mV
", "
30 mV
", "
60 mV
","
300mV
".
Correct selection depends on the sensitivity of the DMS sensor. Sensors
with more than 300 mV input voltage may not be used.
Example: Characteristic value of the strain gage sensor (DMS) according
to the data sheet: 1.41 mV/V
Feed voltage (measured): 9.82 V
Signal from sensor computed at: U
(mV)
= 1.41
.
9.82 = 13.82
Selected input range is "15 mV".
