Description

Woodward 5466-1115 – High-Density Speed and Analog I/O Combo Module

Product Overview

The Woodward 5466-1115 is a MicroNet high-density Speed/Analog I/O combination module designed for industrial turbine control applications. It provides four speed inputs together with twelve selectable analog inputs and four analog outputs, allowing several field signal types to be handled from a single controller module. The speed channels support MPU, proximity probe, or eddy-current sensor applications, while the analog inputs can be configured for 4–20 mA or 0–5 V signals. The four analog outputs provide 4–20 mA service with a maximum load resistance of 600 ohms. Woodward classifies this version as standard accuracy and notes its primary use in steam turbine markets.

Technical Specifications — 5466-1115

Woodward documentation identifies the module as the standard-accuracy version and distinguishes it from the higher-accuracy 5466-1105 used mainly in gas turbine applications.

Key Features and Benefits — 5466-1115

• Combines speed measurement and analog signal conditioning in one high-density module.
• Four speed channels support MPU, proximity, and eddy-current sensing.
• Twelve analog channels accept either 4–20 mA or 0–5 V signals.
• Four 4–20 mA outputs can drive loads up to 600 ohms.
• Intended primarily for steam turbine control applications.
• Can serve as a replacement for older 5466-253 and 5466-316 modules where proportional actuator control is provided separately.

Related Models

5466-1105: High-accuracy Speed/Analog I/O combination module with four speed inputs, twelve selectable I/V inputs, and four 4–20 mA outputs, mainly associated with gas turbine applications.

5466-253: Earlier MicroNet analog combination module used in steam control systems and certain TMR configurations.

5466-316: Legacy analog combination module that can be replaced by the standard-accuracy configuration when actuator control is handled separately.

5466-1051: MicroNet TMR 48/24 high-density discrete I/O module for applications requiring higher-density discrete signal handling.

Installation and Maintenance — 5466-1115

Confirm the MicroNet architecture, module revision, field termination hardware, and application software requirements before installation. Woodward notes that the newer Speed/Analog combination modules use new GAP blocks and require appropriate Coder revisions for the relevant turbine platform.

During maintenance, inspect connectors and field wiring for contamination, loose contacts, or mechanical damage. Record the installed firmware and configuration before replacement. Personally, I would also verify every speed-input sensor type before commissioning because MPU, proximity, and eddy-current wiring are not interchangeable simply because they share the same module.

Product Warranty — 5466-1115

Warranty coverage depends on the supplier and whether the module is new, refurbished, repaired, or surplus. Confirm the quoted warranty period, test report, serial-number traceability, and return conditions before purchase. For critical turbine spares, matching the exact hardware revision and installed control architecture is more important than relying on the part number alone.

The Woodward 5466-1115 remains a useful high-density I/O option for established MicroNet steam turbine control systems where mixed speed and analog signals need to be managed within a compact control architecture.
