GE DS200DTBAG1A Digital Contact Terminal Board
Product Description
The GE DS200DTBAG1A is a Digital Contact Terminal Board (DTBA), part of GE’s Mark V LM Series, engineered for gas turbine control management systems. Classified as a Contact Input Termination Module, it is installed at locations Q11, Q21, and Q51 within digital cores, serving as a critical interface between contact inputs and the TCDA.
Its core function is to route the first 46 contact inputs of a digital core to the TCDA board, with input sense inversion configurable via TCDA IO settings for fail-safe functionality. It draws 125 VDC power via the JY connector and supports two excitation voltage options for contact input via the TB2 terminal board—implemented at the factory. The Mark V LM controller uses its power to provide fuse-isolated, current-limited interrogation voltage for inputs. Jumpers on the board isolate field grounds by cutting interrogation voltage, grouped in 8-contact sets, and require turbine shutdown for adjustments. It also enables TCDA to timestamp contact input status changes within 1ms and runs continuous diagnostics to alert on circuit failures.
Key Features
Mark V LM Gas Turbine Integration: Explicitly designed for Mark V LM gas turbine control systems,
ensuring seamless compatibility with digital cores and TCDA boards.
Configurable Fail-Safe Inputs: Contact inputs can be inverted via TCDA IO Configuration to enable
fail-safe operation, adapting to critical turbine safety
requirements.
Dual Excitation Voltage Support: Factory-set to use either 125 VDC or 24 VDC excitation for contact
inputs, matching diverse system power needs.
Ground Isolation & Safety: Field grounds are isolated using jumpers that cut interrogation
voltage; jumper adjustments are restricted to turbine shutdowns for
safety.
Precise Monitoring & Diagnostics: Enables TCDA to timestamp input status changes within 1ms and runs
continuous diagnostic checks, triggering alerts for circuit
failures to minimize downtime.
Optical Isolation: All contact inputs are optically isolated by the TCDA board,
preventing electrical interference and protecting sensitive control
circuits.
