Systems, which utilize Smart Sectional Controllers (SSC) and Pit
Power Supplies (PPS) for load cell excitation and signal processing.
Most applications use one (1) SSC per section, and one (1) PPS for the entire
platform.
─
This applies until the number and resistance of the cells require a second pit
power supply.
SSC boxes have four (4) terminals.

Two (2) terminals are used for load cells and two (2) for interfacing to other
SSC boxes or terminating to a pit power supply.
