The GE IS220PDIAH1A 336A4940CSP1 is a 24-channel discrete contact input/output (I/O) module designed for the Mark VIe Speedtronic™ turbine control system.
1. Key Functions
Discrete Signal Handling:
Processes 24 digital input/output signals (e.g., contact closures, relay status) for turbine control and monitoring.
Supports both sourcing and sinking configurations for flexible industrial integration.
System Integration:
Interfaces with Mark VIe controllers via ISBus communication.
Compatible with TMR (Triple Modular Redundant) systems for high-reliability applications.
Diagnostics & Protection:
Provides real-time status feedback for each channel (open/closed, fault detection).
Includes galvanic isolation to prevent noise interference in harsh environments.
2. Technical Specifications
Channels: 24 discrete I/O points.
Voltage Range: Typically 24V DC (industrial standard).
Isolation: Channel-to-channel and system-to-field isolation.
3. Applications
Turbine Control: Monitors safety interlocks, valve positions, and alarm contacts.
Power Plants: Integrates with DCS/PLC systems for automated protection logic.
