POWERCELL Connections to DigiTOL Scales with NMOS POWERCELLs and Pit Power
Supplies
For applications in which the POWERCELL PCB is connected to a DigiTOL Scale with
POWERCELL load cells, the JAGXTREME terminal must be wired with the auxiliary power
supply (P/N 0917-0168 for 100/110/120 VAC operation, 0917-0169 for 220/240
VAC operation).
The purpose of the auxiliary power supply is to provide two identical circuits, each with
a 24 VDC power supply output capable of driving up to two Pit Power Supplies. Each Pit
Power Supply can drive a maximum of 12 NMOS load cells. As shown above, the
INDICATOR A and B inputs are connected to the PIT PS outputs. The two circuits are
completely isolated. The only exception is the same 24 VDC power supply output being
used for PIT PS1 and 3. The second 24 VDC supply is shared between PIT PS2 and 4.
