Transition resistances of the connection contacts
The transition resistance values of the connection contacts affect the measurement. The measuring
accuracy can be further increased by a user-side adjustment with the signal connection plugged in.
Validity of property values
The resistor of the bridge is positioned parallel to the internal resistor of the box module and leads
to an offset shifting respectively. The Beckhoff factory calibration will be carried out with the half
bridge 350 Ω, thus the values specified above are directly valid for the 350 Ω half bridge. By
connection of another dimensioned half-bridge is to:
• perform a balancing (offset correction) by the box module itself or the control/PLC on application
side
• or the abstract offset error have to be entered into the balancing parameter S0 of the box
module. Example: a 350 Ω half bridge correlates by the compensated effect of the input resistor
(2 MΩ) during factory calibration 0.26545 %
