Product Overview

The GE DS200RTBAG2AHC is a Relay Terminal Board designed for use in GE's Mark V Speedtronic Turbine Control System, which supports gas, steam, and wind turbine automation. Though the Mark V is considered a legacy system, it was one of the final GE turbine control systems to utilize the patented Speedtronic technology.

This relay board is specifically designed to provide 10 additional relay positions within the control cabinet. It supports both LAN and remote I/O terminal control, making it highly versatile for various GE excitation systems or drive applications.

Note: DS200RTBAG2AHC is an enhanced version of the original DS200RTBAG2, incorporating three significant revisions to improve performance and compatibility.
