WOODWARD LS-5 8440-1946 – Circuit Breaker Control & Protection Module | LS-5 Governor Platform
Engineering Background
The WOODWARD LS-5 series represents a mature, field-proven governor and control platform widely deployed in power generation, turbine control, and industrial circuit protection applications. The 8440-1946 is a dedicated control protection module within this platform, engineered to interface directly with circuit breaker actuation circuits, providing deterministic trip/close logic, fault isolation, and status feedback in demanding industrial environments.
Product Positioning
Designed for procurement engineers sourcing replacement or expansion modules for existing WOODWARD LS-5 governor systems, the 8440-1946 delivers OEM-equivalent performance without the lead times associated with new factory orders. Konmask.com maintains verified stock of this module, supporting both emergency replacement and planned maintenance schedules for power plant operators, EPC contractors, and MRO procurement teams.

- Robust Industrial Design: Engineered to WOODWARD’s industrial-grade standards for vibration, EMI, and thermal cycling tolerance
- Reduced Downtime Risk: Availability from Konmask stock eliminates factory lead times — critical for unplanned outage recovery
- Backplane Integration: Seamless integration with LS-5 system chassis; no additional interface hardware required
- Long Service Life: Designed for continuous-duty industrial operation with minimal scheduled maintenance
System Architecture & Signal Flow
Within the WOODWARD LS-5 platform, the 8440-1946 module occupies the control protection layer of the system architecture. Signal flow is as follows:
- Input Acquisition: The module receives breaker status signals (52a/52b contacts), protection relay trip commands, and governor control outputs via the LS-5 backplane.
- Logic Processing: Onboard control logic evaluates trip/close permissives, interlock conditions, and synchronization status.
- Output Actuation: Discrete output channels drive breaker coil circuits (trip coil / close coil) with appropriate current ratings and timing.
- Status Feedback: Breaker position and fault status are returned to the LS-5 HMI and historian via backplane communication.
- Fault Isolation: On detection of a protection event, the module executes a deterministic trip sequence and latches fault status for operator review.
Sourcing & Quality Verification
- Stock Origin: Sourced from authorized distributors, decommissioned OEM installations, and verified surplus channels

Technical FAQ
Q: Is the 8440-1946 compatible with all LS-5 system revisions?
A: The 8440-1946 is designed for the WOODWARD LS-5 platform. Compatibility with specific system revisions should be confirmed against your existing system’s BOM or WOODWARD documentation. Contact Konmask for pre-purchase compatibility verification.
Q: Can this module be used as a standalone circuit breaker controller outside of an LS-5 system?
A: No. The 8440-1946 is designed for integration within the LS-5 backplane architecture and requires the LS-5 system power supply and communication bus to operate.
Q: What is the typical lead time from Konmask stock?
A: In-stock units ship within 1–3 business days of PO confirmation. Express dispatch available for urgent requirements.
Q: Do you provide a test report or functional verification certificate?
A: Yes. A Konmask inspection report is available for all units. Third-party testing can be arranged at buyer’s cost.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing is available for orders of 3 units or more — request a bulk quotation.
Q: Can Konmask source additional quantities if current stock is insufficient?
A: Yes. Konmask operates an active global sourcing network for WOODWARD components. Submit your requirement and we will provide a sourcing timeline.
