GE IS200GDDDG1A IS200GDDDG1ABA Generator Protection

The IS200GDDDG1A IS200GDDDG1ABA functions as a generator protection board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200GDDDG1A serves as the standard version for generator protection signals. Its variant, the IS200GDDDG1ABA, includes a conformal coating for enhanced circuit protection. Both boards manage generator protection for steam and gas turbine systems.

Core Technical Specifications

This board provides multiple protection input channels for generator monitoring. You will also find trip output channels for emergency shutdowns. The board stores minimal energy but uses capacitors for transient suppression. Meanwhile, the backplane interface handles all power and data transfers.
