Product Description

The DS200RTBAG3AEB is a terminal relay printed circuit board built for GE Speedtronic Mark V turbine control systems. It acts as the signal interface between internal rack control modules and external field wiring, undertaking discrete signal distribution, relay switching and electrical isolation tasks. The board transmits turbine control commands and collects equipment status feedback signals to realize reliable signal interaction between the controller and field actuators.

Equipped with industrial-grade relays and built-in noise suppression circuits, this board is designed to adapt to power plant operating environments with electromagnetic interference and temperature fluctuations. It supports long-term continuous operation and frequent signal switching. Widely adopted as replacement spare hardware, it is used for overhaul and component renewal of aging gas and steam turbine control racks.
