Description
Product Overview
The GE IS220PTCCH1A REV D is a high-precision thermocouple input module within the GE Mark VIe control system, engineered for critical temperature monitoring in industrial automation. This module integrates a dedicated processor and acquisition board to deliver real-time, accurate temperature data acquisition, supporting a wide range of thermocouples (types E, J, K, S, T) and millivolt inputs (-8 to 45 mV span). Designed for harsh environments, the IS220PTCCH1A REV D operates reliably within -22°F to 149°F (-30°C to 65°C) and features robust electromagnetic interference (EMI) shielding. Its seamless integration with the Mark VIe platform enables efficient data transmission via industrial Ethernet protocols, making it indispensable for applications demanding sub-0.25°F measurement accuracy. The module supports simplex, duplex, and triple modular redundant (TMR) configurations, ensuring fault tolerance in mission-critical processes like turbine control and energy generation.

Key Features and Advantages
Ultra-Precision Temperature Sensing
The IS220PTCCH1A REV D achieves industry-leading accuracy (±0.25°F) through its 16-bit ADC and hardware/software filtering, eliminating signal drift in electrically noisy environments like power plants. Dual-stage multiplexing (differential + master) ensures minimal crosstalk during multi-channel data acquisition.
Robust Industrial Design
With conformal-coated PCBs and IP20-rated housing, the module resists humidity, chemical corrosion, and particulate ingress. High common-mode rejection (100 dB) and normal-mode rejection (250 mV RMS) guarantee stable readings amid voltage fluctuations.
Flexible Deployment
Supporting up to 12 thermocouples per module, it scales effortlessly: two modules enable 24 inputs, while three facilitate TMR configurations for safety-critical systems. Auto-diagnostics (RAM, flash, Ethernet port self-tests) and internal power monitoring preempt failures, reducing unplanned downtime.
Seamless System Integration
Native compatibility with Mark VIe controllers allows plug-and-play installation. Real-time data streaming via Ethernet/IP enables rapid response to thermal anomalies in processes like steam turbine overspeed protection.
Application Areas
The GE IS220PTCCH1A REV D is pivotal in industries requiring rigorous temperature control:
- Power Generation: Monitors turbine bearing temperatures and exhaust gases in gas/steam plants, preventing overheating-induced failures.
- Chemical Processing: Tracks reactor vessel and pipeline temps via grounded/ungrounded thermocouples, ensuring reaction stability in corrosive environments.
- Oil & Gas: Deployed in TMR configurations for furnace and distillation column safety systems, where measurement integrity is non-negotiable.
- Manufacturing: Optimizes kiln/furnace operations in cement and metallurgy sectors, leveraging mV input for pyrometer integration.

Installation and Maintenance
Installation Preparation:
Mount vertically on DIN rails using TSVOH1D terminal boards. Maintain ≤0.1Ω ground resistance and isolate thermocouple cables from high-voltage lines (>20 cm separation) to prevent EMI. Validate power supply stability (24–28V DC ±5%).
Maintenance Recommendations:
Clean air vents quarterly with dry compressed air (≤0.3 MPa). Annually calibrate input offsets via Mark VIe software tools. Replace electrolytic capacitors after 50,000 operational hours (≈5.7 years).
