The DS200TBQBG1ACB executes signal routing for high-fidelity turbine monitoring, facilitating the direct interface between field instrumentation and the TCQA/TCQC processor boards. It serves as the physical termination point for diverse inputs, ranging from LVDT position feedback to vibration monitoring probes. The board manages the signal path integrity for analog inputs, ensuring that current loops and voltage signals are correctly referenced to the control system common before being transmitted across the backplane for digitalization.
Frequently Asked Questions
Q: Is this terminal board compatible with both R2 and R3 core configurations?
A: Yes. The board is designed for installation in slot 7 of the R2 and R3 cores, maintaining specific pin assignments for TCQA and TCQC processor board communication.
Q: How should LVDT inputs be wired to this terminal board to maintain signal accuracy?
A: LVDT leads must be connected to the designated terminals with proper attention to phase and amplitude matching. Utilize shielded, twisted-pair cabling and ensure the shield is terminated at the designated ground stud on the cabinet frame to prevent electromagnetic interference.
Field Installation Guidelines
- Verify that all control rack power is de-energized and locked out before initiating module installation.
- Align the board with the slot 7 guides in the R2 or R3 core, ensuring the backplane connectors are correctly oriented.
- Seat the board firmly and tighten the mounting screws to the chassis to maintain environmental integrity and grounding contact.
- Interface external cabling to the terminal blocks, ensuring that JGR and JHR connectors are seated and latched to secure the signal path for vibration and pulse rate monitoring.
- Perform a cold-loop check with a calibrated signal generator to verify that input signals are correctly registered at the processor level before turbine startup.
