Description

Woodward 5466-328

Technical Specifications

  • Product Type: I/O Expansion Module / Signal Conditioning Card.
  • Input Channels: 8 analog inputs (configurable for ±10 V or 4–20 mA).
  • Output Channels: 4 analog outputs (±10 V or 4–20 mA) and 8 digital outputs (24 VDC).
  • Communication: RS-485 (Modbus RTU) or proprietary MicroNet bus.
  • Power Requirement: +24 VDC ±10%, max 2.5 A.

Functional Features

  • High-Noise Immunity: Incorporates differential inputs with >60 dB common-mode rejection and 500 VDC galvanic isolation to prevent false trips from EMI.
  • Flexible Signal Compatibility: Each analog input can be independently configured via software or DIP switches, eliminating the need for external signal conditioners.
  • Seamless Integration: Communicates natively with 505E governors, SLC controllers, or third-party SCADA systems.
  • Diagnostic Visibility: Features LED indicators for power, communication status, and individual channel faults.

Application Scenarios
Widely used in power generation (gas turbines, diesel engines), oil & gas, and marine propulsion applications for extending control system capacity without replacing the entire controller.

Performance Parameters

  • Isolation: 500 VDC channel-to-channel and channel-to-ground.
  • Operating Temperature: -20°C to +70°C.
  • Protection Level: IP20 (for indoor control cabinet use).

Material Composition
Encased in a metal-reinforced thermoplastic housing designed to withstand continuous vibration (up to 5 g) and wide temperature swings. Terminals are screw-clamp type with finger-safe covers.

Structural Characteristics
Compact modular design suitable for DIN rail or panel mounting. The module features a ruggedized exterior to protect internal electronics from harsh industrial environments.

Working Principle
The module conditions incoming analog signals (filtering and amplifying), converts them to digital values via high-resolution ADCs, and transmits the data to the main controller. It also converts digital commands from the controller back into precise analog or digital outputs to drive field devices.

Installation Requirements
Mount on a standard DIN rail or using the optional panel mount bracket. Ensure adequate clearance for ventilation. Connect the shield drain wire to the cabinet’s grounding busbar to maintain signal integrity.

Usage Precautions

  • Always observe ESD (Electrostatic Discharge) precautions when handling the module.
  • Verify that the power supply voltage is within the specified range before applying power.
  • Do not exceed the maximum current ratings for output channels.
