GE DS200TCPDG1B PDM, Switch & Fuse Card

This card is a foundational part of the control system’s power infrastructure, critical for safety and fault tolerance.

  • Power Management: The TCPDG1B is the main hub for distributing incoming power, typically 125 VDC, from the system’s power supplies. It routes this power to various boards in the control rack, including the processors (TCPA boards), I/O modules, and communication cards. This ensures each board receives the necessary voltage to operate correctly.
  • Circuit Protection: The card features 36 fuses, each dedicated to protecting a specific circuit. These fuses are a critical line of defense against overcurrents caused by short circuits in the field wiring or a faulty module. This design isolates the fault, preventing it from damaging the power supply or other sensitive components and maintaining system reliability.
  • Switching Functionality: The board is equipped with eight toggle switches that provide a manual means of control. These switches can be used for selectively enabling or disabling power to individual circuits for maintenance, troubleshooting, or isolation without having to de-energize the entire cabinet.
  • On-Board Diagnostics: For easy troubleshooting, the TCPDG1B includes 36 green “OK” LEDs, one for each fuse. An unlit LED quickly indicates a blown fuse, allowing maintenance personnel to diagnose and resolve power-related issues without extensive testing. The board may also feature red LEDs for other system alerts.
