Description
GE IS200WETBH1BAA Mark VI Speedtronic Wet Terminal Board
Product Description
The IS200WETBH1BAA is a wet terminal board for GE Speedtronic Mark VI turbine control system. Unlike passive dry terminal boards, this wet board integrates field sensor power supply, relay circuits, fuses, voltage regulators and signal conditioning hardware on one PCB. It serves as the electrical interface between field instruments and Mark VI front-side I/O processor cards, delivering conditioned power and sensor signals for flame detection, vibration monitoring, shaft voltage measurement and analog/digital field signals. The board is densely populated with relays, transformers, fuses and protection components, with conformal coating for cabinet environmental protection. It supports simplex and TMR triple modular redundant architectures, designed for continuous, high-reliability operation in power plant turbine control cabinets.
