Load Cell Terminal Block
The load cell terminal block on the MSI-9008 Multiplexer PCA is divided into four sections; TB1A, TB1B, TB1C, and
TB1D.
When connecting load cells, excitation and shielding are shared connections for two channels at a time; i.e. - 1 + 5, 2 + 6,
3 + 7 and 4 + 8. The individual signal lines are separated for each channel. The following table shows the pin out for the
input connector TB1:
