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.
Please observe that applications with high insulation voltages require
sufficient space or insulation to adjoining devices.
Protective measures must be taken against electrostatic
discharges (ESD) when mounting and setting 931S-P1C2D-DC.
2. Application
RTD 3 Way Active Converters 931S-P1C2D-DC are used for galvanic
isolation and conversion of temperature, resistance and potentiometer
signals. Input and output signals are calibrated switch selectable via
DIP switches. It is not necessary to adjust the pre-settable measurement
ranges. A +/- 12.5 % variation can be achieved in the respective range by
switching in potentiometers for zero and span. The analog signal is linear
to the temperature and to the resistance or to the potentiometer setting.

3. Configuring the device
3.1 Tools
A screwdriver with a 2.5 mm blade is required to set the device,
and to connect the conductors to the terminals.
3.2 Open the device
Remove the connector Press the lock lightly
on both sides of the housing to unlock it (1),
remove the upper part of the housing and the
electronics (2).
3.3 Settings
Set input and output ranges, minimum input
values and measuring span via the DIP switches
SW1 and SW2 according to the following tables.
The potentiometers Span (gain) and Zero (offset)
can be activated by the switch SW1/8, accessible
from the front below the cover (3), to finely
calibrate the gain and offset
