GE IS220PRTDH1B RTD Input I/O Pack

Product Description

IS220PRTDH1B is a RTD resistance temperature detector input I/O pack for GE Vernova Speedtronic Mark VIe turbine control system. It offers 8 channels of 3-wire RTD temperature acquisition with 10mA sensor excitation current, paired with matching TRTD terminal board for field sensor wiring. The module is equipped with dual 10/100Mbps full-duplex Ethernet ports for high-speed communication with Mark VIe controller. It supports simplex configuration, conformal coated PCB option for harsh plant environment, operating temperature range -30℃ ~ +65℃. This pack converts resistance signal from platinum RTD sensors into digital temperature data for gas turbine, steam turbine and compressor monitoring and protection.

Key Functions

• 8-channel 3-wire RTD temperature measurement, 10mA constant current excitation
• Dual redundant Ethernet communication interface to Mark VIe controller
• High precision resistance to digital conversion for platinum temperature sensors
• Open circuit, short circuit and sensor fault detection for each RTD channel
• Built-in self-diagnosis, watchdog and module health status reporting
• Supports long cable transmission up to 300 meters for field temperature sensors
• Compact rack-mounted I/O pack design for Mark VIe control cabinet

Application Scenarios

• Gas turbine and steam turbine control & protection systems
• Power plant generator stator and bearing temperature monitoring
• Compressor, pump and rotating machinery bearing temperature measurement
• Oil & gas industry turbomachinery safety monitoring cabinets
• GE Mark VIe distributed I/O rack for power generation control
