GE D20 EME 2400‑21004 Energy Management Expansion Module

The GE D20 EME 2400‑21004 is an energy management expansion module designed for GE D20 substation control and data acquisition systems. It undertakes high‑precision power parameter calculation and energy metering functions, processing voltage and current sampling data to compute active power, reactive power and accumulated energy values for power utility substation automation applications. The part number 2400‑21004 is the hardware reference identifier of this EME module.

This plug‑in module is mounted on the D20 chassis backplane bus and operates in coordination with the D20 main CPU. It uploads processed electrical measurement data to upper‑level SCADA systems for substation monitoring, energy statistics and power quality analysis. Original production has been discontinued. It is widely supplied as aftermarket spare parts for substation control cabinet maintenance and legacy power‑automation system retrofit projects.

6. Global aftermarket spare supply for technical teams maintaining obsolete GE D20 series substation control hardware.

FAQ

1. Q:Can GE D20 EME 2400‑21004 work as standalone unit?
   A:It is an expansion daughter module, must be inserted into D20 chassis and cooperate with D20 main CPU controller, independent operation is not supported.
2. Q:What symptoms appear when module fails?
   A:Loss of energy‑measurement data, abnormal power‑quantity calculation values, D20 system module fault alarm may occur.

3. Q:What software is used for parameter configuration?
   A:Parameter setting and data monitoring need to cooperate with GE D20 official configuration tool together with main controller hardware.
