GE IS220PRTDH1B Packaged RTD Input I/O Pack

Technical Specifications Module Type: RTD Temperature Input Packaged I/O Pack Applicable System: GE Mark VIe Speedtronic Turbine Control System Communication Interface: Dual 10/100Mbps RJ45 Ethernet IONet redundant network Field Interface: Matched RTD terminal board via dedicated connecting cable Power Supply: 28VDC nominal local field power Sensor Support: Industry‑standard Pt100 series RTD resistance temperature detectors Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VIe packaged I/O housing, DIN‑rail mountable Certifications: CE, UL power‑generation industrial component compliance

Functional Features Multi‑channel acquisition of field RTD resistance‑type temperature sensor signals. Precise resistance measurement and conversion into real‑world temperature values. Redundant dual‑Ethernet communication ensures stable temperature‑data transmission to main controller.

Application Scenarios Distributed temperature signal collection for Mark VIe turbine bearing, casing and auxiliary systems. Field‑side temperature condition monitoring for power‑plant gas‑turbine and steam‑turbine units. Spare‑part replacement for existing Mark VIe distributed control installations.

Structural Characteristics Compact metal‑shielded packaged housing suitable for TS‑35 DIN‑rail mounting. Front faceplate equipped with status LED array and dual RJ45 Ethernet ports. Rear 28VDC power connector and dedicated cable interface for RTD terminal‑board connection.

Working Principle RTD sensor resistance signals are routed to matched RTD terminal board and transferred into IS220PRTDH1B. On‑board precision measurement circuit reads resistance value for each channel and converts resistance reading into temperature data.

Installation Requirements Mount module on standard TS‑35 DIN‑rail inside local field‑side enclosure. Connect 28VDC power supply with correct polarity to avoid reverse‑power damage. Wire dual Ethernet ports to redundant IONet control network. Field RTD sensor wiring shall adopt shielded cables and keep distance from high‑voltage power cables.
