4.6.4.6
Connecting load cells to an external supply
If the total resistance of the load cells is ≤75
Ω
(e.g., more than 4 load cells with 350
Ω
),
an external load cell supply is required. In this case, the internal supply is replaced by a
potential-free external supply.
The center of the external supply voltage (0 ext. supply) should be connected to GNDA to
ensure that the voltage reacts symmetrically to 0.
The internal supply is not connected.
Note:
The colors listed here apply for the Minebea Intec load cell and connection cables of
type "PR …"
