Brief Product Description

GE DS200TCQAG1BHF is a high-precision industrial analog I/O control board belonging to the GE Speedtronic Mark V turbine control system series. As a core signal processing component, it undertakes analog signal acquisition, conditioning, conversion and transmission for turbine and generator control loops. This board accurately processes temperature, pressure, flow and vibration analog signals from field transmitters, converting them into digital data for system calculation and executing analog output regulation commands. Featuring industrial-grade signal shielding, built-in circuit diagnostics and conformal coated PCB design, it delivers stable anti-interference performance and long-duration continuous operation in harsh power plant cabinet environments. Fully tested surplus and refurbished GE DS200TCQAG1BHF boards are available for legacy Mark V turbine control system maintenance, I/O board replacement and plant retrofit projects.
