4.3 Connecting the transducer
Important
Transducers with four-wire configuration
If you connect a transducer with a 4-wire cable, you must connect the sense
lead with the corresponding bridge excitation circuit in the transducer plug
(sense line (-) with bridge excitation voltage (-) and sense lead (+) with
bridge excitation voltage (+)
1)
. A cable extension may only be implemented
with 6-wire configuration.
4.3.1 Connecting separate TEDS modules
Important
Single-channel amplifier MLxx (together with connection board AP01i) must
have at least hardware revision 1.32 or higher.
1)
For cable lengths >50m, a resistor of half the value of the bridge resistance (RB/2) must be activated on the transducer instead of each
feedback bridge. If the transducers are calibrated in a 6-wire configuration, resistors must be activated directly into the sense lead.
