GE IS200DTAIH1A IS200DTAIH1ABB Digital Input Terminal PCB

The IS200DTAIH1A IS200DTAIH1ABB functions as a digital input terminal board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200DTAIH1A serves as the standard version for digital signal termination. Its variant, the IS200DTAIH1ABB, includes a conformal coating for enhanced circuit protection. Both boards terminate digital input signals for steam and gas turbine control systems.

Core Technical Specifications

This board provides multiple digital input channels for field device monitoring. You will also find opto-isolation circuits on each input channel. The board stores minimal energy but uses capacitors for contact debouncing. Meanwhile, the backplane interface handles all power and data transfers.
