1. General instructions
• Disconnect power prior to installation
• Installation only by Qualified personnel
• Follow all applicable local and national electrical codes
• Due to potential hazardous voltages in close proximity, use a nonconductive tool and proper PPE when adjusting the potentiometers
on the front panel.
For applications with high isolation voltages, take measures to prevent
accidental contact and make sure that there is sufficient distance or
insulation between adjacent devices!
Appropriate safety measures against electrostatic discharge
(ESD) should be taken during assembly and adjustment work
on the 931S-C4C5D-BC.
2. Application
The 3 Way Active Converters 931S-C4C5D-BC are used for galvanic
isolation and conversion of signals in the range from ±20 mV to ±200 V and
±0.1 mA to ±100 mA. Depending on the model, input and output signals
are permanently set or you can select calibrated ranges by means of
DIP switches. The preset measuring ranges do not have to be fine adjusted.
Other transmission ranges are infinitely adjustable within the ranges
mentioned above using potentio meters. Signal transmission is linear.
By means of the broad-range mains adapter, the units can be powered by
voltages from 22 to 230 V AC/DC.

3. Configuration
3.1 Equipment
A screwdriver with a width of 2.5 mm is required to adjust the unit and to
connect the wires to the terminals.
3.2 Opening the unit
Disconnect the plugs. Disengage the top
part of the housing by carefully pressing the
latches on both sides (1). Pull out the top
part of the housing and the electronics
section until they unlock (2).
3.3 Settings
Set the input and output ranges, offset and
bandwidth using DIP switches S1, S2 and S3 as
indicated in the following tables. When selecting
a variable amplification or offset setting, an
additional adjustment can be made using the
Span (amplification) or Zero (offset) potentio meters located under the top cover (3).

3.6 Setting tool for all input and output values
Definitions: In
min
= smallest input value
In
max
= largest input value
Out
min
= smallest output value
Out
max
= largest output value
OS = output span (take from table on Pg 22)
EV = upper end value (take from table on Pg 22)
1. Select output range of unit (according to table on Pg 22) so that Out
min
and Out
max
are within the output range.
2. Calculate the following auxiliary quantities:
3. Set all DIP switches to OFF.
4. Calculate input range IR, set output range and offset OF with DIP
switches.
4a. If the calculated offset OF does not correspond with an offset which can
be set with the DIP switches, set the closest offset (see table on page 22)
and activate the zero potentiometer (switch 2-5 OFF), short-circuit input
and adjust output to value Out
min
– (In
min
x F).
4b. If the calculated input range IR does not correspond with a range
which can be set with the DIP switches set the largest range within
0.33 x IR … 3.30 x IR (see table on page 21) and activate the span
potentiometer (switch 2-4 OFF), modulate input with value ≠ 0 (see table
on page 21 for terminals) and adjust output to required value (e.g. set
In
max
, adjust to Out
max
).
