IDNet Connections
TO AVOID DAMAGE TO THE PCB OR LOAD CELL, REMOVE POWER FROM THE IND780
TERMINAL AND WAIT AT LEAST 30 SECONDS BEFORE CONNECTING OR DISCONNECTING
ANY HARNESS.
For IDNet base load cells, the IND780 terminal supplies 12 VDC for the new T-
Brick type, and 30 VDC for the legacy PIK-Brick type. When using an IDNet card in
the IND780 terminal, the cable connection from the base is made to a connector
on the rear of the housing. IDNet cards are supplied with a length of cable and a
connector that mates to the connector on the IND780 terminal. The board is shown
in Figure 2-55.
Figure 2-55: IDNet Option Board
Figure 2-56 shows the IDNet harness. One end attaches to the option board, and
the threaded body of the connector mounts in one of the keyed holes in the back of
the Panel or Harsh Enclosure, with its nut on the outside of the enclosure. Route
the harness wire away from any Analog Loadcell Boards to protect the IND780
from external influences. Refer to Figure 2-21 and Table 2-1 for the Harsh
enclosure mounting position.
