within HBM.
6.4 Supply voltage
The transducer must be operated with a separated extra‐low voltage (nominal
(rated) supply voltage 18 to 30 V
DC
). You can supply one or more torque
flanges within a test bench at the same time. Should the device be operated on
a DC voltage network
1)
, additional precautions must be taken to discharge
excess voltages.
The information in this section relates to the self‐contained operation of the
T40B, without HBM system solutions.
The supply voltage is electrically isolated from signal outputs and shunt signal
inputs. Connect a separated extra‐low voltage of 18 V to 30 V to pin 3 (+) and
1)
Distribution system for electrical energy with greater physical expansion (over several test
benches, for example) that may possibly also supply consumers with high nominal (rated) cur­
rents.
