M.E.A. Incorporated Redundant Electronic Control System

Description of Operation:

Each Electronic Control System works independently of each other. The Electronic Control System has built-in finder system, automatic switch over logic on failure of any electronic component, failure of position transducer, servo valve and incoming 4-20 mA control signal. The Electronic Control System can be operated from the main system independantly as the redundant system. By adding the position transducer redundant option and dual coil servo valve, all essential electrical parts to function will be redundant.
