Description

Woodward 2301E

Technical Specifications

  • Power Supply: 24 VDC.
  • Operating Temperature: -40°C to +70°C (-40°F to +158°F).
  • Actuator Output Options: 4-20 mA, 0-20 mA, 0-200 mA, or PWM.

Functional Features

  • PC-Based Configuration: Utilizes Control Assistant or Woodward ToolKit software for flexible application selection.
  • Advanced Data Logging: Records 16 seconds of data at 10-millisecond intervals during shutdown, peak speed, or load detection events.
  • Soft Load Transfer: Supports soft load transfer, automatic idle-to-rated switching, and load rejection/pulse options.

Application Scenarios
Ideal for modernizing engine-generator sets, pump applications, and compressor stations requiring adaptive speed sensing and remote speed/load referencing.

Performance Parameters

  • I/O Expansion: Includes 8 discrete inputs, 4 discrete relay outputs, 2 configurable analog inputs, and 1 configurable analog output.
  • Communication: Dual serial ports (RS-232 for configuration, RS-422 for Modbus RTU control).

Material Composition
Features a newly designed terminal block that accommodates additional I/O, housed in a sheet metal chassis suitable for ordinary or hazardous locations.

Structural Characteristics

  • Status Indicators: Added LED indicators for power and RS-422 communication status.
  • Form Factor: Maintains the exact same footprint and mounting configuration as the legacy 2301D for seamless drop-in replacement.

Working Principle
The microprocessor-based controller uses adaptive speed sensing algorithms to manage engine speed and load. It communicates via Modbus RTU and allows real-time parameter adjustments through its dedicated serial interfaces.

Installation Requirements

  • Direct Replacement: Can be directly substituted for part numbers 8273-1012, 8273-139, and 8273-141 without mechanical modifications.
  • Wiring: Connect the RS-232 port via a 9-pin connector to a PC for initial software configuration.

Usage Precautions

  • Software Dependency: Configuration and parameter changes require an external PC and proprietary Woodward software.
  • Thermal Limits: Ensure the installation environment does not exceed the maximum +70°C operating temperature.
