GE IS200EXTBG1A IS200EXTBG1AAA External Termination PCB

The IS200EXTBG1A IS200EXTBG1AAA functions as an external termination board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EXTBG1A serves as the standard version for field signal termination. Its variant, the IS200EXTBG1AAA, includes a conformal coating for extra circuit protection. Both boards terminate external field signals for steam and gas turbine controls.

Core Technical Specifications

This board provides multiple termination points for field device wiring. You will also find surge suppression circuits on each input channel. The board stores minimal energy but uses capacitors for noise filtering. Meanwhile, the backplane interface handles all power and data transfers.
