GE IS200TREGH5B IS200TREGH5BDC Mark VI Discrete I/O PCB

The IS200TREGH5B IS200TREGH5BDC functions as a discrete input and output board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200TREGH5B serves as the standard version for discrete signal processing. Its variant, the IS200TREGH5BDC, includes a conformal coating for extra circuit protection. Both boards manage digital I/O signals for steam and gas turbine controls.

Core Technical Specifications

This board provides twenty-four discrete input channels for field device status. You will also find sixteen discrete output channels on this same PCB. The board stores no significant energy but uses capacitors for signal debouncing. Meanwhile, the backplane connector handles all power and data transfers.
