Railway Signal System Wiring Diagram for DM-1 Control Panel

Detailed electrical wiring diagram for a railway signal control system designated as 1-DM-1#. The schematic illustrates interconnections between various signal modules including IP/IIP/IIIP/IVP series components and relay interfaces. Key features include:

Signal Connections:
– Multiple IP-series (1-4) and IIP-series (1-4) signal connections
– IIIP and IVP series signal controller interfaces
– Dedicated backup circuit paths (marked as ‘备用’)

Terminal Blocks:
– Terminal specifications including 135-12BL(6), 90-4S(2), and 1015-16BL(4)
– GT/GTH grounding terminals
– XB2 terminal block configurations

The diagram contains coordinated numbering schemes for terminal connections with specific cross-references to field connection points (F1-series numbered terminals). This drawing is part of the Beijing-Guangzhou Line Yanggezhuang and Zhuzhou Station Interlocking Equipment Renovation Project, with drawing number 2300-G4200133.01.
