Woodward LR20949 Electronic Module

Overview

Configured for signal measurement and control execution in Woodward generator control platforms, the Woodward LR20949 (LR20949 electronic module) provides direct physical and electrical execution for voltage and current monitoring functions. The module processes field measurement signals and interfaces with control systems for generator and power management applications.

Hardware Specifications

Actuator Loop Feedback and Generator Control Interface

The Woodward LR20949 supports electrical measurement functions required for generator monitoring and control circuits. The module receives voltage and current input signals, then transfers processed data to the associated controller.

In addition, Woodward control architectures typically apply actuator loop feedback response management to maintain stable interaction between measurement devices, controllers, and final control elements. The LR20949 integration depends on the configured Woodward system platform and application parameters.

Frequently Asked Questions

Q: Does the LR20949 support direct voltage and current measurement?
A: Yes. The module is associated with measurement applications using voltage and current sensing functions. The exact input configuration depends on the installed Woodward system design.

Q: Does the LR20949 provide Modbus RTU and CANbus communication?
A: Communication capability depends on the specific system configuration. The module may operate with Modbus RTU or CANbus interfaces within compatible Woodward control architectures.

Q: Can the LR20949 operate in redundant controller configurations?
A: The module itself does not define redundancy behavior. Redundant operation depends on the controller architecture, wiring configuration, and system firmware compatibility.

Field Installation Guidelines

• Install the LR20949 according to the applicable Woodward control system wiring documentation.
• Mount the module on a stable DIN-rail or panel surface with adequate clearance for wiring access.
• Separate signal wiring from high-voltage power cables to reduce electrical interference.
• Connect cable shields according to the grounding requirements of the installed control cabinet.
• Verify voltage input, current input, and communication wiring before system energization.
• Confirm controller firmware compatibility before integrating the module into an existing control network.
