Description
Product Overview
The GE IS220PDIOH1B is an advanced Discrete Input/Output (DIO) Control Board designed for GE’s Mark VIe Speedtronic Turbine Control System, engineered to provide high-speed digital signal management and interface control for critical industrial applications. As the successor to the IS220PDIOH1A, this module builds on its predecessor’s capabilities with enhanced cybersecurity features, extended compatibility with newer ControlST software versions, and improved diagnostic tools. Its rugged design with conformal coating ensures resilience against moisture, dust, and electromagnetic interference (EMI), making it ideal for offshore wind farms, oil & gas platforms, and high-vibration industrial environments .
Featuring 24 digital inputs and 12 relay outputs, the GE IS220PDIOH1B supports hot-swappable redundancy (simplex/DMR configurations) and integrates seamlessly with GE’s ControlST v11.0+ software for programmable logic control and diagnostics. The board interfaces with dual Ethernet ports (10/100 Mbps) and Ionet communication networks, enabling real-time data exchange with distributed I/O systems and plant-wide SCADA platforms. Its 4 ms hardware filtering and optical isolation (1500 VAC) ensure accurate signal acquisition and noise immunity, critical for maintaining system reliability in harsh conditions .
As part of the Mark VIe HazLoc-certified subseries, the GE IS220PDIOH1B is approved for use in hazardous locations when paired with compatible terminal boards (e.g., IS200TDBSH2A or IS200TDBTH2A). This modular design allows for flexible system expansion, supporting up to three redundant modules in Triple Modular Redundancy (TMR) architectures for SIL-rated safety applications .
