DS200DTBAG1A GE Mark VLM Digital Contact Terminal Board

Product Description

The DS200DTBAG1A is a Digital Contact Terminal Board manufactured by General Electric for the Mark VLM turbine control system. It provides the termination interface for digital contact inputs and connects the first 46 contact inputs in the digital core to the TCDA board. Furthermore, it supports configurable contact sensing, isolated interrogation voltage, and input status monitoring with timestamp recording.

Digital Contact Input Interface

The DS200DTBAG1A terminates contact input signals and routes them to the TCDA board for processing. Its designated installation positions are Q11, Q21, and Q51 in the digital core. The contact inputs connect to the TCDA board, which monitors their status changes.

In addition, the TCDA I/O configuration allows users to invert the contact sense when configuring fail-safe contact input functionality. This setting changes how the controller interprets the contact state.

Contact Input Excitation Voltage

The Mark VLM controller supplies interrogation voltage to the contact input circuits. Depending on the factory configuration, the excitation voltage can be 125 VDC or 24 VDC. The TB2 terminal board supports these two supply options for the DTBA and DTBB terminal boards within the digital core.

The controller provides fuse-isolated and current-limited interrogation voltage. Furthermore, jumpers on the DTBA and DTBB terminal boards can disconnect this voltage to isolate field grounds. These jumpers serve contact input groups of eight channels. Therefore, any jumper changes must be performed only when the turbine is not operating.

Input Monitoring and Diagnostics

The TCDA board assigns a timestamp to each contact input status change within 1 ms. When an input is configured for event logging, the operator interface printer can record the corresponding timestamp. This information helps maintenance personnel identify the sequence and timing of contact input events.

In addition, the controller continuously performs diagnostic checks on contact input circuits. If a circuit fails these checks, the system generates an alarm to indicate the fault condition.

Frequently Asked Questions

Q: What is the main function of the DS200DTBAG1A?

A: The DS200DTBAG1A provides the termination interface for digital contact inputs in the Mark VLM system. It connects the first 46 contact inputs in the digital core to the TCDA board for signal monitoring and processing.

Q: Does the DS200DTBAG1A support both 24 VDC and 125 VDC input excitation?

A: Yes. The terminal board arrangement supports either 24 VDC or 125 VDC excitation. However, the required voltage configuration is implemented at the factory and should be checked before replacement.

Q: Can the DTBA jumpers be adjusted while the turbine is running?

A: No. The jumpers control interrogation voltage isolation for groups of eight contact inputs. Changes to these jumpers should only be made when the turbine is not operating.
