Features:
- Backup Protection Terminal Board Provides Independent Turbine Emergency Control.
- Compatible With GE PPRO I/O Pack And SPRO/TPRO/TREA Terminal Boards For Redundant Monitoring.
- Supports Wide Input Voltage Ranges And Sensor Interfaces To Ensure Reliable Operation.
General Electric IS200SPROH1ADD Backup Protection Terminal Board is a high-reliability solution for turbine emergency protection in Mark VIe Speedtronic systems. By interfacing with PPRO I/O packs and terminal boards such as SPRO, TPRO, and TREA, it provides independent monitoring and control of turbine speed, voltage, and emergency stop signals.
This terminal board operates with a 28 V dc power supply at 0.37 A, handling PT inputs (0–138 V ac), speed inputs (–15 to +15 V dc), and sensor power outputs (24 V dc, 25 mA). TREA connections allow voltage monitoring, E-stop functionality, and contact outputs rated for high-current operation, enabling rapid shutdowns and equipment protection.
The IS200SPROH1ADD ensures system redundancy and improves operational safety. When deployed across multiple PPRO I/O packs and terminal boards, it enhances turbine protection architecture, reduces downtime, and maintains reliable emergency control in both gas and steam turbine installations. By integrating this board, operators can achieve safer, more reliable, and resilient turbine operation.
The IS200SPROH1ADD General Electric Backup Protection Terminal Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
