Key Features & Benefits
-
Customer Input Terminals: Two 24-point pluggable barrier terminal blocks (H1A, H2A) or 48 pluggable Euro-style box terminals (H3A, H4A) simplify field wiring.
-
Passive Pulse Rate Devices: Nine sensors (three per X/Y/Z) measure turbine speed via a toothed wheel, ensuring accurate speed feedback.
-
Jumper Blocks: Fan one set of three speed inputs to all three PPRO I/O packs for synchronization and redundancy.
-
Output Contacts: TMR voted contacts at 24 V dc (H1A, H3A) and 125 V dc (H2A, H4A) provide robust trip actuation.
-
Voltage Detection Circuits: Four circuits (24–125 V dc) monitor the trip string for integrity.
-
Daughterboard Connectors: Enable optional feature expansion.
Industry Applications
The IS200TREAH2AED is specifically designed for turbine emergency trip applications in power generation and industrial processing. It monitors trip strings, provides redundant output contacts, and interfaces with PPRO I/O packs to ensure rapid, reliable shutdown.
For example, in a steam turbine installation, the board's voltage sensors monitor power supply and solenoid voltages, alerting operators to potential issues before they escalate. In gas turbine applications, the passive pulse rate devices deliver precise speed signals, enabling early overspeed detection—critical for protecting expensive rotating equipment.
Installation & Setup Guidance
Mount the IS200TREAH2AED securely in the Mark VIe cabinet, ensuring adequate clearance for airflow and cable routing. Connect customer inputs via the pluggable terminal blocks, and verify that all wiring matches the board's labeling. For speed sensing, position the passive pulse devices close to the toothed wheel, maintaining the recommended gap. After wiring, test each trip channel individually before placing the system online.
Maintenance & Reliability
Regularly inspect terminal blocks for tightness and signs of corrosion. Check that all jumper blocks remain properly seated. Because the board operates in harsh environments, verify that the ambient temperature stays within -30 to 65°C. Periodically test the voltage detection circuits and trip relay sensing to confirm they respond correctly to fault conditions. Proactive maintenance extends service life and minimizes unplanned downtime.
Compatibility & Integration
The IS200TREAH2AED integrates with the GE Mark VIe control system, specifically working with PPRO turbine I/O packs. It is designed for TMR (Triple Modular Redundant) configurations, ensuring high availability. The board's pluggable terminals and daughterboard connectors allow for flexible expansion.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system uses the Mark VIe platform and that the IS200TREAH2AED matches your trip voltage requirements (24 or 125 V dc). Confirm the physical dimensions (33.0 cm x 17.8 cm) fit your cabinet layout. For guaranteed authenticity and fast delivery, choose PLC Source PRO as your trusted supplier.
