GE IS220PDOAH1A 3364940CSP2｜Discrete Output I/O Pack｜
Output Control Capabilities
Professional Relay Output Control
Provides 12 discrete relay output channels, compatible with both solid-state and electromagnetic relay terminal boards. The module meets actuator driving requirements and is optimized for single-redundant system architectures and space-efficient installations.
Redundancy Support
Fully compatible with Mark VIe single, dual, and triple-modular redundant (TMR) system architectures. The module can be configured redundantly with controllers to enhance control output reliability, making it suitable for critical applications in power generation and petrochemical industries.
Advanced Diagnostic Capability
Real-time LED indicators display module, communication, and channel status. The integrated infrared diagnostic serial port supports local diagnostics, enabling rapid detection of faults such as:
Field voltage loss
Terminal board mismatch
Channel or communication abnormalities
Hot-Swap Capability
Supports live replacement in accordance with system specifications, minimizing maintenance downtime and improving overall system availability.
Industrial-Grade Reliability
Designed with multilayer PCBs and high-reliability surface-mount components, offering strong resistance to vibration and electromagnetic interference. The module is suitable for long-term operation in harsh industrial environments.
Typical Applications
Gas and Steam Turbine Control Systems
Relay command output for fuel valve actuation
Inlet guide vane (IGV) positioning
Safety interlock and protection actions
Supports turbine start-up, shutdown, and protection logic.
