GE IS200SPROH2A IS200SPROH2ADD Speedtronic Protection

The IS200SPROH2A IS200SPROH2ADD functions as a protection I/O board for turbine controls. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200SPROH2A serves as the standard version for protection signal management. Its variant, the IS200SPROH2ADD, includes a conformal coating for enhanced circuit durability. Both boards manage protection I/O functions for steam and gas turbine systems.

Core Technical Specifications

This board provides eight protection input channels for safety monitoring. You will also find six protection output channels for actuator control. The board stores minimal energy but uses capacitors for signal conditioning. Meanwhile, the backplane connector handles all power and data transfers.
