IS200TSVCH1AED | GE Electric Mark VI series high-voltage analog input module

IS200TSVCH1AED | GE Electric Mark VI series high-voltage analog input module

Product Description:

The IS200TSVCH1AED is a Thermocouple/High-Level Voltage Analog Input Module designed by GE for its Mark VI series Speedtronic gas/steam turbine control systems. Its primary function is to condition, digitize, and transmit signals from thermocouples (TC) or high-level DC voltage sources (e.g., ±10V DC) to the Mark VI controller for critical monitoring and control. It provides isolated, high-resolution measurement of temperature or process variables essential for turbine protection, efficiency optimization, and operational sequencing.

Product Parameters / Specifications:

Series: This module belongs to GE’s Mark VI family of turbine control systems, the generation preceding Mark VIe. It operates within the Mark VI I/O architecture.

Key Features:

1. Multi-Signal Input: Supports a wide range of industry-standard thermocouple types and high-level DC voltage signals.
2. 12 Isolated Channels: Each channel is electrically isolated for safety, noise immunity, and independent configuration.
3. High Resolution & Accuracy: 16-bit A/D conversion provides precise measurement for critical monitoring.
4. Built-in Cold Junction Compensation (CJC): Essential for accurate thermocouple readings, integrated per group of inputs.
5. Advanced Signal Conditioning: Includes filtering, high input impedance, and excellent noise rejection (CMRR & NMRR) for reliable signals in electrically noisy plant environments.
6. Comprehensive Diagnostics: Detects sensor faults (open circuit), signal over-range/under-range, and provides visual status per channel.
7. Software-Configurable per Channel: Each channel can be independently configured for signal type, range, filtering, and alarms via the Mark VI toolset (ToolboxST).
8. Industrial Durability: Designed for harsh power plant conditions (temperature, humidity, vibration, EMI).
9. Backplane Integration: Communicates seamlessly with the Mark VI controller via the VME backplane.

Function/Role: The IS200TSVCH1AED acts as the primary interface for acquiring temperature and high-level DC voltage signals critical to turbine operation. It performs essential signal conditioning (amplification, filtering, isolation, CJC), converts the analog signals to high-resolution digital values, and transmits this data reliably to the Mark VI controller for monitoring, control logic, alarming, and protection functions.

Purpose/Use: This module is essential for measuring key operational parameters on the turbine and its auxiliary systems. Its typical uses include:

1. Turbine Temperature Monitoring: Measuring exhaust gas temperature (EGT/TTxx), bearing temperatures, lube oil temperature, seal oil temperature, compressor discharge temperature, blade path temperatures (for large frames).
2. Process Temperature Monitoring: Measuring steam temperatures, cooling water temperatures, generator winding/bearing temperatures.
3. High-Level Voltage Inputs: Monitoring outputs from transmitters or transducers providing signals like valve position (LVDT/RVDT secondary), pressure (4-20mA converted to voltage via resistor), level, vibration (proximitor gap voltage), or speed (magnetic pickup signal conditioning output).
4. Protection & Alarming: Providing the critical input data needed by the Mark VI controller to trigger protective trips (e.g., high exhaust temperature, high bearing temperature) or generate alarms.
5. Control Inputs: Supplying temperature and voltage feedback signals used in closed-loop control algorithms (e.g., temperature control loops).

Application Fields / Industries:

• Power Generation (Primary Domain): 
  • Gas Turbine Power Plants
  • Steam Turbine Power Plants
  • Combined Cycle Power Plants (CCPP)
