I/O Density Scaling and Field Signal Routing

The DS200TBQBG1ACB provides the field termination layer for GE Mark V turbine control I/O circuits. The terminal board routes analog and discrete signals from external sensors, switches, and actuators to processor interface boards including TCRA and TCCB modules.

The board supports I/O density scaling within the Mark V cabinet by organizing multiple field circuits into structured terminal connections. Its passive signal routing design maintains wiring separation and simplifies connection between field devices and control processing hardware.

Frequently Asked Questions

Q: Is the DS200TBQBG1ACB responsible for signal processing?
A: No. The board is a passive terminal interface module used for field wiring termination and signal routing.

Q: What types of signals can be connected through the TBQB terminal board?
A: The board supports discrete input/output signals and analog field signals according to the Mark V cabinet configuration.

Q: Does the terminal board require an external power supply?
A: No. The DS200TBQBG1ACB does not contain active processing circuits and does not require an independent power connection.

Field Installation Guidelines

Install the DS200TBQBG1ACB in the designated Mark V cabinet mounting location and verify terminal identification before field wiring connection. Confirm all screw terminals are properly tightened to maintain stable electrical contact.

Route analog signal cables separately from high-current power conductors and switching circuits to minimize electromagnetic interference. Use shielded cables where required, and terminate shields according to the turbine control cabinet grounding practice.

Before installation or maintenance, isolate system power and verify field circuits are de-energized. Check terminal assignments, signal polarity, and connection references against the approved Mark V wiring documentation before system startup.
