Product Introduction

The 5441-413 is the physical relay interface between a Woodward controller and external discrete loads. Woodward’s current Industrial Turbine Products Catalog identifies 5441-413 as a 32-channel discrete output relay FTM, with one Form C contact per relay and a contact rating of 10 A at 28 VDC.  In the documented Woodward architecture, the FTM is selected together with the appropriate output module and cable combination; it is not a standalone PLC output card.

For asset management, that distinction matters. Woodward lists 5441-413 under Relay FTMs and specifies Table K for the associated cable selection, while a separate DIN-rail relay option, 1751-6091, is listed for the same general 16-channel class of application.  A like-for-like 5441-413 replacement therefore preserves the established field-termination arrangement and relay architecture. Do not substitute a visually similar relay interface without checking channel count, contact form, current rating, and the associated Woodward output module (especially where the relay contacts are switching solenoids or other inductive loads).

Core Technical Specifications

Woodward’s published catalog is the primary source for the 32-channel, 1 Form C, 10 A at 28 VDC specification and the Table K cable-selection reference. ([turn327205search20])

🚨 Global Compliance & Industry Certifications

The 5441-413 is a field termination relay assembly, so certification should be assessed against the complete Woodward control system and installation.

• CE Mark: No standalone CE declaration specific to 5441-413 was established from the records reviewed.
• UL/cUL: No independent 5441-413-specific UL/cUL listing was established from the documentation reviewed.
• ATEX/IECEx: No standalone ATEX or IECEx certificate specific to 5441-413 was established.
• Marine Approvals: No 5441-413-specific DNV, ABS, or Lloyd’s Register approval was established.
• EMC: Compliance depends on the complete control cabinet, cable routing, grounding, suppression, and connected loads.
• Contact-Rating Compliance: The published 10 A at 28 VDC value should not be extrapolated to AC switching or higher-voltage DC applications. ([turn327205search20])

For a plant audit, record the actual relay markings, contact rating, control-system drawing reference, and installed wiring configuration. A relay rated for 10 A at 28 VDC is not automatically suitable for every 10 A load.

Verify specific lot certifications with OEM.

🚨 Long-Term Storage & Asset Preservation Guide

Keep relay contacts and connectors protected from moisture. The 5441-413 contains a large number of electromechanical relay contacts, where oxidation can increase contact resistance or produce intermittent switching.

Store the module in a clean, dry environment. A practical warehouse target is below 60% RH, avoiding condensation and corrosive atmospheres. Do not store the relay FTM next to chlorine, sulfur compounds, solvents, or other corrosive chemicals.

Protect the cable/terminal interface from mechanical impact. With 32 relay channels, there are many connection points that can be damaged by a dropped carton or improper stacking. Keep the assembly immobilized and protect all connectors during storage.

Do not cycle the relays repeatedly just to “exercise” them. Uncontrolled cycling provides little preservation value and can unnecessarily consume mechanical relay life. Instead, perform a controlled functional test before deployment.

Record the relay and terminal configuration. Photograph the complete module, labels, connector positions, and any installed wiring accessories before placing the asset into long-term inventory. This creates a useful baseline for future MRO inspection.

Physical Installation Prerequisites

The 5441-413 is an industrial field termination relay assembly, not a DIN-rail PLC output module. Woodward’s catalog separately identifies the 5441-413 relay FTM and the 1751-6091 DIN-rail 16-channel relay option.

Before installation:

• Confirm the exact 5441-413 part number.
• Verify the associated Woodward output module and cable-selection table.
• Confirm all 32 channels against the approved I/O schedule.
• Verify the required Form C contact arrangement.
• Check the field-load voltage and current before applying the published 10 A / 28 VDC contact rating.
• For solenoids, contactors, and other inductive loads, verify that the installed suppression scheme is appropriate.
• Inspect relay terminals and connectors for oxidation, bent contacts, cracked housings, and loose hardware.
• Verify cabinet grounding and protective bonding.
• Keep relay-load wiring segregated from low-level analog and communications wiring where the cabinet design permits.
• Maintain enough service space to access all 32 channels and replace wiring without disturbing adjacent equipment.
• Do not impose a generic 50 mm clearance requirement; use the actual Woodward cabinet layout and cooling arrangement.
• Verify the mating cables before insertion. Woodward specifically associates this relay FTM with Table K cable selection
• Before energization, perform point-to-point continuity checks on critical relay outputs.
• After installation, test each safety- or shutdown-related relay function individually.

Buyer’s FAQ

Q1. What HS tariff code should be used for Woodward 5441-413?
A: A current industrial inventory record identifies HS tariff code 8538907080 for 5441-413, but a supplier’s classification should not automatically be treated as the legally binding code in another jurisdiction. Because the item is a dedicated electrical relay/interface component, the final country-specific classification should be confirmed by the importer or customs broker.

Q2. Does Country of Origin equal the export warehouse location?
A: No. One current inventory record identifies the United States as the country of manufacture for 5441-413.For customs compliance, use the origin supported by the actual unit or manufacturer’s traceability documentation rather than the location from which the spare happens to ship.

Q3. How should I package and insure a 5441-413 for international freight?
A: Protect the module in moisture-resistant packaging, immobilize the relay assembly inside a rigid carton, shield connectors and terminals against impact, and prevent internal movement during transit. One current inventory source reports approximately 3.9 kg for the item, so freight planning should use the actual packed weight after packaging is complete.  For a shutdown-critical spare, insure the shipment for the documented replacement value.

Q4. Does 5441-413 have the latest firmware pre-loaded?
A: No. The 5441-413 is a 32-channel relay field termination module, not a processor or intelligent controller. Woodward’s catalog describes its relay contacts and interface role rather than any firmware function.Compatibility is determined by the associated output module, cable arrangement, relay contact configuration, and field load.

Q5. Can I hot-swap 5441-413?
A: Do not treat it as a routine hot-swap module. The assembly interfaces directly with external electrical loads, and its relay contacts may be connected to energized circuits. Isolate the relevant circuits according to the approved Woodward maintenance procedure, verify absence of hazardous voltage, document every channel connection, and perform point-to-point and unctional checks before returning the equipment to service.
