Woodward 5466-258 MicroNet HDD (High Density Discrete) Module

Description:

The Woodward 5466-258 MicroNet HDD (High Density Discrete) Module is a legacy I/O module for MicroNet control systems, providing high-density discrete input/output functionality. It was originally used in NetCon, MicroNet Simplex, and TMR configurations with 040 or Pentium NT‑based CPUs. This module has been obsoleted and replaced by newer HDDIO modules (e.g., 5466‑1050 for simplex, 5466‑1158 for Coder 4 systems) which offer improved self‑test routines and memory mapping. The 5466‑258 remains available as a spare part for existing installations that cannot immediately upgrade to modern CPU platforms. It is compatible with existing Field Termination Modules (FTMs) and works with Coder versions 2.x or 3.x.

Key capabilities

• High Density Discrete I/O for MicroNet control systems

• Compatible with NetCon, MicroNet Simplex, and TMR configurations

• Works with 040 and Pentium NT CPUs (Coder 2.x or 3.x)

• Interfaces with existing Woodward FTMs (Field Termination Modules)

• Suitable for legacy system spare parts and maintenance

• Provides discrete input/output signals for industrial control logic

Applications

• Legacy MicroNet turbine and engine control systems

• Replacement spare part for existing HDD modules in NetCon/Simplex/TMR racks

• Discrete I/O for sequencing, interlocking, and monitoring functions

• Systems that cannot yet upgrade to 5200‑based MicroNet Plus or TMR configurations

Quality Assurance

100% brand new original. 1-year warranty. In stock for fast delivery (1-3 weeks).
Note: This is a legacy module; for new designs, Woodward recommends upgrading to HDDIO modules (e.g., 5466‑1050, 5466‑1158).

Frequently Asked Questions

Q1: What is the main function of the 5466-258 module?
A1: It is a High Density Discrete (HDD) I/O module for MicroNet control systems, providing discrete input/output channels for industrial logic.
Q2: Has this module been replaced?
A2: Yes. It has been obsoleted and replaced by HDDIO modules: 5466‑1050 (simplex) for Coder 5.04+, or 5466‑1158 (simplex) for Coder 4.06+ systems with 5200 CPUs.
Q3: Can I use this module with a modern MicroNet Plus system?
A3: For 5200 and P1020 CPU systems, you should use the newer HDDIO modules (5466‑1050 or 5466‑1158). The 5466‑258 is intended only for legacy 040/Pentium NT systems running Coder 2.x or 3.x.
Q4: Is the 5466-258 compatible with existing FTMs?
A4: Yes, it works with the same Field Termination Modules (FTMs) used by the original HDD modules.
Q5: What should I do if I need a replacement for a 5466-258 in a Coder 4 system?
A5: Woodward recommends using the HDDIO module 5466‑1158 (simplex) or 5466‑1156 (TMR) as a direct drop‑in replacement for Coder 4.06+ systems.
