Strain gauge weighing module

The feed voltage of the bridge is generated from the back wall bus of the TB20 and amounts to 5 V with a maximum 70 mA load. The voltage output is protected with an internal, reversible fuse against overload and short circuit. Weighing cells with a maximum of 72 Ω can be connected. The external bridge feed of the load cell is possible.
The bridge voltage can be measured on the load cell with 6-wire connection. The measured value is incorporated into the calculation of the measurement value. Controlled by the application, wire break detection can also take place by feeding test current into the measurement channel.
