GE IS220PTURH1B Turbine - Specific Primary I/O Trip Pack for Mark VIe Speedtronic Turbine Control

Product Description

The GE IS220PTURH1B is a Turbine - Specific Primary I/O Trip Pack (PTUR, Revision B) engineered for GE Mark VIe and Mark VIeS Speedtronic turbine control systems, acting as a core interface for turbine protection signals in gas and steam turbine applications. It connects field safety devices (overspeed sensors, temperature/pressure switches, vibration transmitters) to the main control system, supporting simplex/TMR configurations and pairing with IS200TRPAS1A terminal boards. The module has conformal - coated PCB for anti - corrosion, dual Ethernet ports for communication, isolated signal channels, and redundant 24VDC power input compatibility. It operates stably in -40°C to 85°C temperature ranges, complies with IEC 61010 safety standards, and offers IP20 front - panel protection, suitable for long - term use in power generation, oil & gas, and industrial turbine control scenarios.

Key Functions

The IS220PTURH1B provides core turbine protection I/O capabilities: Primary trip signal processing for field safety devices to trigger emergency shutdown (ESD) when safety thresholds are exceeded; Support for TMR/simplex system configurations to meet different redundancy requirements; Isolated signal channels to prevent cross - talk, ground loops, and EMI/RFI interference, ensuring signal accuracy; Compatibility with IS200TRPAS1A terminal boards for seamless field device connection; Dual Ethernet ports for real - time data transmission and remote diagnostics; Conformal - coated PCB for enhanced reliability in harsh industrial environments; Real - time fault diagnostics for open/short circuit detection and module health monitoring; Redundant 24VDC power input support to avoid protection system failure during power abnormalities.

Application Scenarios

The IS220PTURH1B is ideal for turbine protection I/O tasks in mission - critical industrial applications: Power generation (thermal, nuclear, combined - cycle plants) for gas/steam turbine overspeed, over - temperature, and over - pressure protection, ensuring safe operation of generating units; Oil & gas upstream/midstream for compressor turbine trip control, pipeline pressure safety interlocks, and wellhead turbine protection; Industrial turbine systems (chemical, pulp & paper, mining) for process - related turbine safety monitoring and control, guaranteeing operational compliance and asset protection; TMR system retrofits and upgrades, replacing old I/O trip packs to enhance system reliability; Turbine control system expansion, adding redundant protection channels to meet safety integrity level (SIL) requirements; Hazardous location applications when paired with IS200TRPAS1A terminal boards, adapting to various harsh industrial environments.
