Product Overview

The GE DS200DTBAG1A is a digital contact input terminal board for the SPEEDTRONIC Mark V LM turbine control system. It brings field contact signals into the digital I/O core and routes the first 46 contact inputs to the TCDA board for processing. The DTBA board also carries contact-interrogation power and provides a power connection to the associated DTBB expansion board. This makes it the field-signal interface for a defined group of turbine status, alarm and control contacts. 

Technical Specifications

Features

• Terminates the first 46 contact inputs in a digital I/O core
• Routes contact signals to the TCDA digital I/O board
• Carries contact-interrogation power for field inputs
• Provides a power connection to the DTBB expansion board
• Includes five jumpers for isolating contact-input groups  

Industries Served
-Power Generation: Connects discrete status, alarm and control contacts in Mark V LM gas-turbine control systems.
-Oil and Gas: Supports contact-signal monitoring where Mark V LM-controlled turbines drive site equipment.
-Industrial Utilities: Handles field contact inputs on facilities that use Mark V LM turbine-generator equipment.  

Frequently Asked Questions

1. What does the DS200DTBAG1A do in a Mark V LM system?
It terminates field contact inputs and passes the first 46 signals in its digital core to the TCDA board.
2. Does this board process the contact inputs itself?
No. DTBA provides the termination and signal path; the TCDA board conditions and processes the contact states.
3. What is the difference between DTBA and DTBB?
DTBA handles the first 46 contact inputs. DTBB is the expansion termination board for the last 46 inputs in the same digital core.
4. Can contact sense be inverted for an application?
Yes. Contact-sense inversion is configured in the TCDA I/O configuration, rather than on the DTBA terminal board.
