Digital Speed Control Module MRD1G5MA by Woodward

Product Description

Overview

The MRD1G5MA is a compact digital speed control module manufactured by Woodward for precise electronic speed regulation of prime movers.
It is designed to control turbines, engines, compressors, pumps, and fans where stable RPM and fast dynamic response are required.

The module combines analog control inputs, PWM output drive, and industrial communication interfaces, making it suitable for modern control panels and distributed control architectures.

Functional Description

The MRD1G5MA regulates rotational speed by processing analog command signals and generating a PWM output to drive actuators or fuel control devices.
Its digital control architecture ensures stable speed control under varying load conditions, start-up sequences, and transient disturbances.

The module is commonly deployed in systems where reliability, compact size, and integration flexibility are critical.
