About this file
This document is a terminal block wiring diagram for the Knoxville Utilities Board (KUB) Halls Substation Control Panels project, specifically detailing the SCADA (Supervisory Control and Data Acquisition) Rack #1 terminal block configuration. The technical schematic depicts a comprehensive wiring diagram for digital input (DI) points, with five terminal blocks (TB1-TB5) representing DNP digital input points ranging from point #0-119. The diagram methodically maps out connection points, slot assignments (AX2_SLOT_B through AX2_SLOT_F), and indicates precise numerical relationships between input connections.
The technical drawing appears to be part of a broader substation rebuild and control system upgrade, with meticulous attention to electrical connectivity and signal routing. The document is dated 3/26/25 and is part of project D-18922, suggesting a planned infrastructure modernization effort for the Halls Substation. While specific pricing details are not present in this technical drawing, the document represents a critical component of the electrical infrastructure design that would be integral to the overall control panel procurement process outlined in KUB's bid #3855.
