Woodward 8441-1138 Multi-Function Relay Module

Overview

The Woodward 8441-1138, also cataloged as the 8441-1138 Multi-Function Relay Module, provides electrical switching and relay logic execution for Woodward control platforms requiring configurable output handling and protection interlocks.

Hardware Specifications

Actuator Loop Feedback Response and Relay Control Characteristics

The Woodward 8441-1138 supports relay-based signal execution within engine and generator control architectures. The module processes configured control commands and transfers electrical states through relay contacts for connected field devices.

In addition, Woodward relay modules within this application category are designed to maintain defined actuator loop feedback response behavior. The module supports controlled switching actions for protection circuits, alarm outputs, and operational interlocks.

The 8441-1138 can operate as part of a governor or power management system where relay output timing and electrical isolation influence system response. Proper configuration of relay logic prevents unintended switching conditions during equipment operation.

Frequently Asked Questions

Q: Does the Woodward 8441-1138 support direct power switching for high-current loads?
A: The module provides relay switching functions. External contactors or interface devices may be required when connected loads exceed relay contact ratings.

Q: Can the 8441-1138 be installed in a redundant control configuration?
A: Redundant operation depends on the complete Woodward control system architecture and configured application design. The relay module itself does not define system redundancy behavior.

Q: What installation factors affect relay signal integrity?
A: Field wiring separation, grounding practices, shielding methods, and correct terminal connections affect relay signal performance in industrial environments.

Field Installation Guidelines

Install the Woodward 8441-1138 inside a suitable industrial control enclosure with protection from moisture, dust, and excessive vibration.

Separate relay wiring from high-voltage power conductors and variable-frequency drive cables to reduce electrical interference. Use proper grounding methods for the control cabinet and follow the system wiring documentation.

Verify terminal assignments before applying power. Confirm relay output states through the configured control logic before connecting external equipment.

Maintain appropriate cable routing practices for actuator feedback and control circuits. Inspect all connections after installation to ensure secure mechanical fastening and correct electrical continuity.
