I/O Density Scaling and Analog Processing

The DS200TCCBG1BED extends the analog processing capacity of the GE Mark V platform through additional RTD, thermocouple, current, and voltage measurement channels. The onboard signal conditioning circuitry performs local conversion of field analog signals before transferring processed data through the control architecture.

The board uses GE industrial control I/O density scaling methods to increase sensor channel availability while maintaining compatibility with Mark V control racks. The onboard Intel 80196 microcontroller manages local scanning, conversion handling, and diagnostic processing.

Frequently Asked Questions

Q: What types of field signals can be connected to the DS200TCCBG1BED analog inputs?
A: The board supports differential analog inputs for RTD, thermocouple, 4-20 mA transmitter signals, and +/-10 V voltage inputs.

Q: Does the DS200TCCBG1BED provide isolation between field wiring and control electronics?
A: Yes. The board provides 1500 V field-to-logic isolation for separation between external analog signals and internal control circuits.

Q: Is firmware stored directly on the board hardware?
A: Yes. The board uses socketed EPROM devices for firmware storage and calibration data management.

Field Installation Guidelines

Install the DS200TCCBG1BED in the designated GE Speedtronic Mark V rack location and verify connector identification before applying power. Confirm that JCC, JDD, JEE, and 3PL connections match the approved wiring documentation.

Analog signal cables should be routed separately from high-voltage and high-current conductors to reduce electromagnetic interference. Shielded instrumentation cables should be used where required, with cable shields terminated according to the control cabinet grounding design.

After installation, verify field input polarity, RTD and thermocouple wiring configuration, and analog channel assignments. Perform the required calibration procedure using the onboard reference points before returning the turbine control system to service.
