Products Description
GE IS200SDIIH1ADB Mark VIe Digital Input Terminal Board in stock
GE IS200SDIIH1ADB is a high-speed digital input terminal board for GE Mark VIe turbine control DCS system. It provides galvanic isolated digital signal acquisition and high-precision SOE sequence of events timestamping for breaker, relay and valve limit switch signals.
This board features multi isolated input channels, on-board signal filtering and status LED indicators. It communicates with the main turbine controller through rack backplane bus. It is discontinued legacy spare widely used for gas turbine and steam turbine control system maintenance replacement in power and oil & gas industries.
