Description
DS200PCCAG6A: Product Overview
The GE DS200PCCAG6A is an RST extended analog terminal board designed for integration into GE’s Mark V series of turbine control systems. As a critical component of the Mark V ecosystem, it enables extended analog signal termination and conditioning for field devices (e.g., LVDT position sensors, thermocouples, pressure transmitters) and communicates processed signals to the Mark V controller.
Role in Automation Systems:
Positioned as an “extended signal interface” in the Mark V architecture, the DS200PCCAG6A performs two primary functions:
-
Signal Termination: Provides additional analog input/output (I/O) channels to support growing system demands (e.g., adding more sensors or actuators in a turbine control system).
-
Signal Conditioning: Filters, amplifies, and scales raw analog signals from field devices to ensure accuracy and consistency before transmitting them to the Mark V controller.
Core Functionality:
-
Extended Signal Support: Builds on the capabilities of standard Mark V analog I/O boards (e.g., TCQA) by adding more channels for LVDT, thermocouple, 4–20 mA, and voltage signals.
-
Hardware Configuration: Uses jumpers (e.g., J1–J8) to select signal types, configure output ranges (e.g., 4–20 mA vs. 0–20 mA), and enable test modes (e.g., RS232 port for card testing).
-
Communication: Transmits processed signals to the Mark V controller via the 3PL data bus and exchanges generator/line signals with other I/O boards (e.g., TCQC) via the JE connector.

Platform Benefits (Mark V Series):
The DS200PCCAG6A leverages GE’s Mark V platform, which is renowned for:
-
Reliability: Industrial-grade components and a rugged design ensure 24/7 operation in harsh turbine hall environments (e.g., high temperature, vibration).
-
Scalability: Supports expansion with additional terminal boards to accommodate growing system demands (e.g., adding more sensors or actuators).
-
Integration: Seamlessly integrates with Mark V controllers and other I/O cores (R1, R2, R3), reducing setup time and effort.

Core Features & Customer Value
1. Extended Signal Capacity:
The DS200PCCAG6A provides additional analog I/O channels beyond standard Mark V boards, allowing engineers to expand system capabilities without replacing existing hardware. For example, in a gas turbine control system, this means adding more LVDT sensors to monitor blade positions or thermocouples to measure exhaust gas temperature, improving control precision.
2. Flexible Configuration:
Hardware jumpers enable customization of signal types and output ranges, reducing the need for software changes. For instance, configuring the milliamp output range (20 mA vs. 200 mA) via J5/J6 allows the board to interface with different actuators (e.g., small valves vs. large pumps), saving time and money during installation.
3. Reliable Communication:
The 3PL data bus and JE connector ensure seamless communication with other Mark V components, minimizing latency and ensuring real-time signal transmission. This reliability is critical for turbine control, where delayed signals could lead to equipment damage or downtime.
4. Rugged Design:
The board’s operating temperature range (-40°C to +70°C) and compact form factor make it suitable for harsh turbine hall environments. Its DIN rail mounting option simplifies installation in crowded control cabinets, reducing setup time and effort.
