GE IS220PDIAH1B Mark VIe Discrete I/O Pack (PDIA Series)

Product Description

The GE IS220PDIAH1B is a dedicated discrete I/O pack engineered for the GE Speedtronic Mark VIe turbine control system, acting as a critical interface between field sensors/actuators and the control network in power generation and heavy industry. It features 24 isolated discrete input channels to collect on/off signals from emergency stops, limit switches, and status indicators, with 24 VDC nominal voltage (max 28.6 VDC) and 32 VDC max contact input voltage for broad compatibility. Equipped with dual 100MB full - duplex Ethernet ports, it enables high - speed redundant communication with Mark VIe controllers, supporting simplex/dual/triple - redundant system architectures for maximum availability. Certified for hazardous areas (ATEX, UL), it operates reliably in harsh industrial environments (-30°C to 65°C), integrates seamlessly with GE terminal boards (e.g., IS200STCIH8A, IS200TBCIH2C), and offers hot - swappable functionality for minimized downtime, making it ideal for gas/steam turbine control, compressor monitoring, and industrial process automation.

Key Functions

The IS220PDIAH1B delivers robust discrete I/O and communication capabilities for Mark VIe systems: 24 isolated discrete input channels for reliable collection of field on/off signals (e.g., safety interlocks, equipment status); Dual redundant 100MB Ethernet ports for high - speed data transmission and seamless integration with Mark VIe control networks; Support for simplex/dual/triple - redundant system configurations to ensure operational continuity during component failures; Hot - swappable design allowing module replacement without system shutdown, reducing maintenance - related downtime; Isolated signal processing to prevent cross - talk and fault propagation, enhancing system stability; Hazardous area certification (ATEX, UL) for safe operation in explosive environments; Compatibility with multiple GE terminal boards for flexible wiring and system expansion; LED status indicators for real - time diagnostics of channel health and communication links.

Application Scenarios

The IS220PDIAH1B excels in mission - critical industrial control applications: Gas/steam turbine control systems for monitoring safety interlocks, valve positions, and turbine status signals to enable precise operational control and emergency shutdowns; Power generation plants for integrating boiler feed pump status, generator breaker signals, and auxiliary equipment interlocks into the Mark VIe control network; Oil & gas compressor control for collecting pressure switch, temperature alarm, and anti - surge valve position signals to ensure safe and efficient compression processes; Petrochemical refineries for linking emergency shutdown (ESD) systems, burner management (BMS) interlocks, and process valve status to the central control system; Industrial process automation for discrete signal acquisition in manufacturing lines, material handling systems, and water/wastewater treatment plants; Mark VIe system retrofits and expansions to replace legacy I/O modules, improving communication speed and system reliability; Hazardous area installations requiring certified I/O interfaces for safe signal processing in explosive atmospheres.
