It interfaces with turbine protection signals and supports speed monitoring, overspeed detection, and emergency trip logic. The listed configuration includes three pulse-rate or speed inputs, dual redundant Ethernet ports, and compatibility with specified turbine control terminal boards.\u003c\/p\u003e\n\u003ch3\u003eFunction and Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe IS220PTURH1A processes turbine protection inputs and interfaces with the primary turbine trip logic. Its speed-monitoring function accepts signals from passive or active pickups, allowing the control system to monitor shaft speed and evaluate overspeed conditions. The supplied specifications also identify support for Geiger-Muller or optical flame detection sensor interfaces.\u003c\/p\u003e\n\u003cp\u003eThe module uses a dual ARM Cortex processor architecture and provides dual redundant 100Base-TX Ethernet ports for communication with the Mark VIe control system. The Ethernet configuration provides two network connections; the exact redundancy behavior and network topology should be confirmed against the applicable system documentation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIS220PTURH1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMark VIe Speedtronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTurbine Specific Primary Trip I\/O Pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Revision\u003c\/td\u003e\n\u003ctd\u003eA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstruction Manual\u003c\/td\u003e\n\u003ctd\u003eGEH-6725R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor Architecture\u003c\/td\u003e\n\u003ctd\u003eDual ARM Cortex processors (as supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Function\u003c\/td\u003e\n\u003ctd\u003eTurbine protection input and output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeed Input Frequency Range\u003c\/td\u003e\n\u003ctd\u003e2 Hz to 20,000 Hz (as supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeed Sensing Accuracy\u003c\/td\u003e\n\u003ctd\u003e0.01% of speed reading (as supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eDual 100Base-TX Ethernet ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Input\u003c\/td\u003e\n\u003ctd\u003e28 VDC nominal, supplied via terminal board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Power Consumption\u003c\/td\u003e\n\u003ctd\u003e7.0 W (as supplied; verify against the installed configuration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConformal Coating\u003c\/td\u003e\n\u003ctd\u003eYes (as supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-30 to +65 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95%, non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.84 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eGE Mark VIe control system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eTerminal Board and Installation Configuration\u003c\/h3\u003e\n\u003cp\u003eThe IS220PTURH1A mounts on a compatible turbine control terminal board rather than operating as a standalone field-wiring module. The I\/O pack connects to the terminal board through a high-density connector, while its Ethernet ports provide the communication interface to the control network. The documented Mark VIe configuration includes the TTURH1C terminal board; GE documentation also identifies an IS200TRPAH1A terminal board combination for specified primary trip applications.\u003c\/p\u003e\n\u003cp\u003eBefore replacing an installed unit, verify the terminal board part number, turbine protection architecture, field signal assignments, and controller configuration.

It interfaces with turbine protection signals and supports speed monitoring and primary trip functions according to the configured terminal board and control application.\u003c\/p\u003e\n\u003cp\u003eQ: Which terminal board is compatible with the IS220PTURH1A?\u003c\/p\u003e\n\u003cp\u003eA: TTURH1C is a documented associated terminal board. GE documentation also identifies the IS200TRPAH1A combination for specified applications. Confirm the actual terminal board and protection configuration before selecting a replacement.\u003c\/p\u003e\n\u003cp\u003eQ: Can the IS220PTURH1A be replaced without checking the system configuration?\u003c\/p\u003e\n\u003cp\u003eA: No. Verify the exact part number, terminal board, controller configuration, firmware requirements, and signal assignments before replacement. Do not assume that a different revision or another turbine protection I\/O pack is interchangeable.\u003c\/p\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":41450951016538,"sku":"IS220PTURH1A","price":205.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/IS220PTURH1A.jpg?v=1740999945","url":"https:\/\/www.plcmasters.com\/products\/ge-is220pturh1a-primary-turbine-trip-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
