GE D20ME-VME

Quick Introduction
The GE D20ME-VME is a modular Remote Terminal Unit (RTU) controller built on a VME-based architecture. It is designed for mission-critical monitoring and control applications in utilities and industrial infrastructure. Known for its robustness and long service life, the D20ME-VME supports reliable data acquisition, control logic execution, and secure communications in distributed control environments.

Where It Fits in a System

Rather than acting as a simple I/O device, the D20ME-VME functions as a central RTU controller. It gathers field data from connected I/O modules, processes logic locally, and communicates with SCADA or control centers. The VME architecture allows modular expansion and flexible system design, making it suitable for geographically distributed installations.
