The 5501-365 (Part Number: 5501-365) is a versatile multi-function interface module designed for the Woodward MicroNet™ digital control system. This module serves a dual purpose in turbine and engine control architectures: it acts as a high-speed Magnetic Pickup Unit (MPU) for speed sensing and as a high-precision Analog I/O interface. The 5501-365 (Model: 5501-365) is specifically engineered to provide the fast response times and stable signal processing required for prime mover governing, load sharing, and critical machinery protection.
Correcting common classification errors: while often mistakenly listed as a power supply due to chassis similarities, the 5501-365 (Governor I/O: 5501-365) is primarily a signal conditioning and input/output module. It processes high-frequency speed pulses and modulates analog control signals (up to 25 mA) to drive actuators and fuel valves. Built for mission-critical industrial environments, it provides the Expertise and Trustworthiness (E-E-A-T) necessary for 24/7 operation in power generation, oil & gas, and marine propulsion sectors.
The 5501-365 (5501-365) is optimized for high-density analog signal processing and frequency acquisition.
