Technical Specifications and Board Design
This I/O processor board manages data acquisition for GE Mark V turbine systems. The GE DS200TCQEG2A DS200TCQEG2AED handles analog and digital signal processing independently. You can install this board into any standard Mark V rack slot position. Its dedicated processor offloads I/O tasks from the main turbine controller. The board weighs approximately 0.59 kilograms. Its dimensions measure 28 cm in height, 18 cm in width, and 2.5 cm in depth.

Processing Capabilities and Data Handling
The onboard processor handles all I/O scanning independently from the main CPU. This architecture reduces the main controller’s workload significantly. The GE DS200TCQEG2A DS200TCQEG2AED pre-processes analog signals before transmission. It performs scaling, filtering, and limit checking on all input data. The board buffers I/O data and updates the backplane every 5 milliseconds. A green LED indicates proper processor operation and communication status. The board detects overrange and underrange conditions on all analog inputs.
Analog and Discrete I/O Integration
Eight high-resolution analog inputs accept signals from turbine sensors and transducers. Four analog outputs drive actuators, positioners, and governors accurately. The GE DS200TCQEG2A DS200TCQEG2AED provides sixteen discrete inputs for status monitoring. Sixteen discrete outputs control auxiliary devices like pumps and fans. The board performs automatic calibration on all analog channels periodically. Each discrete output includes short-circuit protection and current limiting. A yellow LED indicates activity on each discrete output channel.
Installation and Operational Guidelines
You must insert this board into a dedicated slot in the Mark V rack. The backplane supplies 5V, +15V, and -15V DC power automatically. The GE DS200TCQEG2A DS200TCQEG2AED draws approximately 320 mA from the 5V supply. It draws an additional 90 mA from each of the ±15V rails. You must use shielded twisted-pair cables for all analog connections. This practice prevents electrical noise from corrupting low-level sensor signals. The board requires no external battery for normal operation. It stores no configuration data independently from the main controller.
