5501-371 | Woodward | MicroNet Simplex MPU & AIO FTM Module

Product Overview

The Woodward 5501-371 Rev C is a MicroNet Simplex MPU & AIO FTM Module from Woodward's MicroNet control system family. It integrates Microprocessor Unit (MPU) and Analog Input/Output (AIO) functionality with Field Termination Module (FTM) capabilities in a single compact module. Designed for simplex (non-redundant) configurations, it provides real-time control and analog signal processing for turbine and engine control applications where cost-effective, reliable control is required.

FAQ

Q: What does MPU & AIO FTM mean?
A: MPU = Microprocessor Unit (control processor); AIO = Analog Input/Output; FTM = Field Termination Module (wiring interface).

Q: Is this module redundant?
A: No, it is a Simplex (non-redundant) design. For TMR redundancy, use MicroNet TMR modules (e.g., 5466-318).

Q: What revision is this?
A: Rev C. Verify revision compatibility with your existing MicroNet system.

Model Selection Tips

• 5501-371 Rev C = Simplex MPU + AIO + FTM integration
• Use for non-critical or cost-sensitive applications where simplex control is acceptable
• For TMR redundant control, consider 5466-318 or 5466-350 CPU modules
• Verify MicroNet chassis slot compatibility before ordering
• Confirm analog I/O channel count meets your sensor/actuator requirements
