Product Overview
The IS200VRTDH1DAC is a high-precision Resistance Temperature Device (RTD) Input Board developed by General Electric for the Speedtronic Mark VI and EX2100 control platforms. This module is engineered to provide high-accuracy thermal monitoring for critical turbine and generator components. By utilizing advanced multiplexing technology and specialized signal conditioning, the board converts raw resistance data from field-mounted RTDs into digitized temperature values. Designed for mission-critical industrial environments, the IS200VRTDH1DAC ensures that thermal transients are detected with deterministic speed, supporting both standard monitoring and rapid protective trip functions.
Advanced Hardware Engineering and Acquisition Logic
The IS200VRTDH1DAC architecture focuses on signal purity and high-speed data conversion through a sophisticated hardware stack:
-
Multiplexed Excitation: Supplies a 10 mA DC multiplexed excitation current to field RTDs. This non-continuous current pulse minimizes sensor self-heating while ensuring accurate resistance measurements.
-
VCO-Based Conversion: Employs a Voltage-Controlled Oscillator (VCO) type A/D converter, featuring voltage-to-frequency converters and sample counters for superior noise rejection.
-
Dual-Speed Scanning: Supports multiple sampling rates, providing 4 samples per second in Normal Mode and up to 25 samples per second in Fast Mode for rapid thermal response.
-
Broad Sensor Compatibility: The onboard Digital Signal Processor (DSP) features software linearization libraries for 15 distinct RTD types, ensuring versatile field instrument support.
-
Interference Suppression: High-frequency decoupling is applied to all signal inputs to mitigate electromagnetic interference (EMI) typical in power plant environments.
-
Fault Detection and Recovery: Integrated out-of-range monitoring identifies short circuits and open loops instantly. Faulty channels are isolated to protect the integrity of the scan and can be automatically restored after a 20-second cooling period.
-
Physical Metrics: A slim VME-style board weighing 0.3 kg with a physical footprint of 2 x 18.5 x 26.1 cm.
Mission-Critical Industrial Applications
The IS200VRTDH1DAC is deployed where thermal accuracy is a prerequisite for system safety and equipment longevity:
| Deployment Scenario | Operational Benefit |
| Generator Stator Monitoring | Tracking winding temperatures across multiple phases to prevent insulation breakdown. |
| Bearing Temperature Tracking | Providing high-speed fast-scan monitoring for turbine bearings to detect lubrication failures. |
| TMR System Redundancy | Operating in Triple Modular Redundant (TMR) R, S, and T racks for fail-safe thermal voting. |
| Deterministic Data Flow | Synchronizing samples with the power system frequency to eliminate aliasing and overlapping interference. |
| EX2100 Excitation Support | Interfacing with temperature sensors in excitation transformers and power bridge cooling systems. |
