GE’s D25 is a flexible, modular, and upgradable automation controller, suitable for both large and small substation automation projects in either new or retrofit situations. The D25 provides the tools and flexibility necessary to create customized automation and control applications including; communications & data concentrator, automation controller, metering & sequence of events fault recording, and transformer monitoring & control.
The D25 controller replaces multiple devices with a single unit. Unified design reduces wiring and maintenance costs. The D25 controller retrieves data from legacy and third-party devices such as relays, transfers it to a host or enterprise system, monitors and runs diagnostics of primary equipment and expands to meet future physical and functional station requirements.
