An electromechanically-assisted control system for use in a second-stage regulator. Regulator control assembly ( 20' ), also referred to as all-electronic (AE) assembly ( 20' ), includes an electromechanical actuator (EMA) sub-assembly ( 22 ) for controlling airflow through single air supply line ( 23 ). EMA sub-assembly ( 22 ) includes electronically controllable actuator (ECA) ( 34 ), which removably seals EMA orifice ( 36 ) in wall ( 30 ) of pilot chamber ( 32 ). ECA ( 34 ) is electrically connected with and controlled by control electronics ( 38 ). The control electronics include programmable microprocessor ( 40 ), which is electrically connected with charge and discharge electronics ( 42 ), both of which are electrically connected with power supply ( 44 ). All-electronic (AE) assembly ( 20' ) has only an EMA sub-assembly and no mechanical actuator sub-assembly.
