Product Introduction

The 8444-1019 belongs to Woodward’s UMT 1 measuring-transducer family, where electrical measurements are converted into standardized signals for higher-level control and monitoring systems. The A6 package is intended for multi-parameter electrical measurement, with analog outputs and communication capability available according to the exact configuration (important when replacing an older generator or power-distribution measurement device).

Physical verification matters with this part. Confirm the 8444-1019 number, revision letter, input rating, and terminal arrangement before installation. A part-specific listing identifies the unit as UMT1, revision E, with 24 VDC auxiliary supply, 5 A AC current input, and a -20°C to +70°C operating range.

Core Technical Specifications

Woodward 8444-1019

Woodward’s published UMT 1 documentation specifies Class 0.5 accuracy, true-RMS measurement, configurable analog outputs, 24 VDC auxiliary power, and the 96 × 72 × 130 mm housing.

Global Compliance & Industry Certifications

Potential compliance considerations include:

• CE Mark — applicable to the UMT 1 product family when incorporated according to the manufacturer’s installation requirements.
• UL/cUL considerations — verify the exact product revision and approval marking before claiming North American certification.
• ATEX/IECEx: Do not assume hazardous-area approval from the part number alone. The complete installation, enclosure, wiring, and associated equipment must satisfy the applicable hazardous-location requirements.
• Marine approvals: The UMT 1 family has applications in power-generation and marine environments, but any DNV GL or other marine approval must be verified against the exact revision and installation configuration.
• RoHS: Verify compliance against the manufacturing date and revision.

The measurement device can be connected directly to electrical circuits carrying potentially hazardous voltages and currents. Proper isolation, fusing, grounding, and cabinet protection are therefore more important than the nominal module dimensions.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

• Keep the 8444-1019 in its original ESD-safe protective packaging and protect the rear terminal area from dust and moisture. The LCD face should also remain protected from abrasion.
• Maintain storage humidity below 60% RH whenever practical. Condensation is particularly undesirable around measurement terminals and PCB assemblies.
• Avoid repeated power-up testing merely to verify shelf inventory. If functional testing is required, use a controlled test setup with the correct voltage/current inputs and calibrated instrumentation.
• Record the revision letter, serial number, input rating, and calibration status in the asset register. This matters because UMT 1 variants use different electrical input configurations.

Physical Installation Prerequisites

• Install the unit using the appropriate front-panel mounting arrangement.
• Provide sufficient rear clearance for terminal wiring and heat dissipation.
• Maintain approximately 50 mm of practical clearance around the housing where cabinet layout permits; do not obstruct ventilation.
• Keep measurement wiring physically separated from high-current switching conductors where possible.
• Use appropriately rated fuses or protective devices for voltage and current measurement circuits.
• Verify the 24 VDC auxiliary supply polarity before energizing.
• Confirm that the installed unit’s input configuration matches the system’s voltage and CT secondary rating.
• Connect protective grounding and signal shields according to the cabinet’s electrical design.
• Do not assume that a visually identical UMT 1 unit has the same input configuration. Check the nameplate.

Buyer’s FAQ (Logistics & Compliance Focus)

Q: What HS Tariff Code is commonly used for Woodward 8444-1019?

A: Measuring transducers can fall under different HS classifications depending on their primary measurement function and national customs interpretation. HS 9030 may be considered for electrical measuring/checking instruments, but the final tariff code should be confirmed by the importer or customs broker.

Q: Does the Country of Origin affect this spare part’s import documentation?

A: Yes. COO affects customs clearance, duty treatment, trade documentation, and asset traceability. Match the declared origin against the commercial invoice, packing list, and certificate of origin when one is required.

Q: Is shipping insurance worthwhile for a UMT 1?

A: Yes, particularly for international freight. The LCD, PCB, terminal assembly, and measurement circuitry can suffer impact or moisture damage even when the plastic housing shows little external damage.

Q: Does the 8444-1019 have the latest firmware pre-loaded?

A: This is a measurement transducer rather than a modern PLC-style controller. Firmware should not be treated as the primary compatibility criterion. Verify the hardware revision, input configuration, analog-output configuration, and communication option against the installed UMT 1 specification before replacement.
