Product Description

The DS200RTBAG2AFB is a terminal relay printed circuit board designed for GE Speedtronic Mark V turbine control systems. It acts as an interface terminal board between the main control modules and on-site field wiring, responsible for relay signal switching, signal terminal distribution and electrical isolation. The board transfers digital control signals to drive external actuators and feeds back equipment status signals to the turbine main controller.

Designed with industrial-grade relay components and signal isolation circuits, this board can withstand frequent switching operations and resist electromagnetic interference in power plant environments. It supports long-term continuous operation under rated working conditions. As an important terminal spare part, it is commonly used for maintenance and component replacement of aging gas and steam turbine control racks.
