Description
- Product Model: IS220PRTDH1A
- Manufacturer: GE
- System Platform: Mark VIe
- Power Supply Voltage: 28 V DC nominal (minimum 27.4 V DC at input), with tolerance for industrial transients to sustain stable operation.
- Power Consumption: Typically under 10 W, promoting efficient integration in control cabinets with minimal heat generation.
- Operating Temperature Range: -30 °C to +65 °C, extended industrial range for reliable performance in turbine environments.
- Storage Temperature Range: -40 °C to +85 °C, allowing secure long-term storage of spares.
- Humidity Range: Up to 95% non-condensing, suitable for humid power plant conditions.
- Communication Interfaces: Dual RJ-45 10/100 Mbps Ethernet ports, supporting redundant IONet connectivity for deterministic data exchange.
- RTD Input Channels: 8 channels, supporting 2-wire, 3-wire, or 4-wire RTD configurations (e.g., Pt100, Ni100, Cu10) with lead wire compensation.
- Resolution: 14-bit ADC, providing fine granularity for accurate temperature discrimination in critical monitoring points.
- Accuracy: High precision linearization and conversion, typically ±0.5 °C or better across range (depending on RTD type and wiring), essential for bearing, exhaust, or steam temperature control.
- Lead Resistance Compensation: Up to 15 Ω maximum per lead (3-wire/4-wire), minimizing errors from long cable runs in field installations.
- Isolation Type: Galvanic isolation on inputs to prevent ground loops and enhance noise rejection in electrically noisy turbine settings.
- Mounting Type: Plugs directly onto RTD terminal boards (e.g., IS200STRT or TRTD series) via DC-37 connector, with DIN-rail or panel options for vibration resistance.
- Environmental Protection: Conformal-coated PCB; rated for Class I, Division 2 hazardous locations (Groups A–D), enabling use in potentially explosive atmospheres.
- Certifications and Standards: Compliant with IEC 61000 EMC series, IEC 61131-2, hazardous area approvals, and GE Speedtronic qualification for turbine controls.
- Mean Time Between Failures (MTBF): High (>200,000 hours typical for Mark VIe I/O packs), supporting continuous operation in critical assets.
- Electromagnetic Compatibility (EMC): Meets industrial standards for immunity and emissions, reducing interference near generators or power electronics.
- Diagnostics: Channel health monitoring, open/short detection, lead resistance verification, and Ethernet-based fault reporting via IONet.
Technical Architecture & Functional Positioning
The IS220PRTDH1A operates as a specialized RTD input pack at the field interface layer of the Mark VIe system. It mounts onto a dedicated terminal board for sensor wiring, excites RTD elements with low constant current, measures resistance accurately, applies linearization curves (e.g., Callendar-Van Dusen for Pt100), and digitizes signals with 14-bit resolution. Conditioned temperature values are then transmitted over redundant IONet Ethernet to the controller, enabling precise closed-loop temperature regulation.
Core technologies include precision current sources for excitation, high-resolution ADC for conversion, lead compensation algorithms to nullify wiring effects, and galvanic isolation to combat EMI prevalent in turbine halls. The pack supports simplex operation, focusing on reliable single-path temperature acquisition for non-redundant monitoring points.
These attributes solve key challenges in turbine temperature control: delivering accurate, drift-free readings for critical parameters like bearing metal, exhaust gas spread, or steam chest temperatures; compensating for field wiring resistance in long runs; and providing diagnostic visibility into sensor or wiring faults to prevent false alarms or missed trips. Integration with Mark VIe diagnostics allows proactive maintenance, reducing unplanned outages while maintaining thermal efficiency.
