2635 Field Portable Wire Harness Test Analyzer

Additional Information

The DIT-MCO Model 2635 Field-Portable Wiring Analyzer is designed for maintenance, troubleshooting, fabrication, and field-service applications where portability and access to the Unit Under Test (UUT) are critical. Its compact, rugged design allows technicians to bring automated wiring test capability directly to aircraft, vehicles, equipment, and other systems without relying on long or specialized adapter cables.

The Model 2635 supports testing for continuity, resistance, insulation, voltage, capacitance, and dielectric integrity, with test stimulus up to 1500 VDC and 2 A. Depending on configuration, the system supports up to 800 test points and test speeds of up to 5,000 tests per minute.

Built for Portable Testing

The Model 2635 is designed to operate in locations where larger test systems may be impractical. Its portable configuration is well suited for tight working areas such as aircraft cockpits, maintenance bays, flight lines, repair depots, and other field environments.

The system is housed in a lightweight molded case designed to resist impact, moisture, and corrosion, helping protect the analyzer during transportation and use in demanding environments.

Flexible Computer & Operator Interface

The Model 2635 can operate from a compatible computer, notebook, or tablet through a network interface. For a fully self-contained configuration, an optional embedded controller and LCD touchscreen can be integrated directly into the system.

A USB connection supports transfer of test data, while operators can use either the touchscreen or a wireless keyboard to interact with the test software.

NETS Software

The Model 2635 uses DIT-MCO's Next Generation Electrical Test Suite (NETS) for test creation, execution, diagnostics, and troubleshooting.

Standard software capabilities include:

• NETS
• Syntax Checker (SYNCHK)
• Diagnostics
• Check Sum
• Wire List Importer

Additional software options include:

• TestAssistant® II
• APG/Wiresort
• Checksum (CHKSUM)
• Language Translators

Functional Testing & Latching Matrix

The Model 2635 includes 10 Latching Matrix (LM) points, allowing the test system to switch power circuits under program control. These points can be used to operate relays and other active components during functional testing.

This capability allows the Model 2635 to perform more than basic continuity and insulation testing by supporting applications where electrical components must be energized or controlled as part of the test sequence.

Multiple Interface Options

The Model 2635 can be configured with several test interface types to suit different applications and existing test adapters, including:

• D-Ribbon
• D-Sub
• DL1-ZIF
• MIL Circular

Additional hardware options include a continuity probe, expansion switching, battery operation, and an embedded CPU with LCD touchscreen.

Model 2635-B Battery-Powered Configuration

The Model 2635-B extends the portable platform with battery-powered operation for applications where facility power may not be readily available.

Its lithium battery provides approximately six hours of runtime, and the system can continue operating while connected to external power and charging. The 2635-B supports up to 800 points of switching, continuity measurement down to 0.01 Ω, and high-voltage testing up to 1500 VDC.

Designed for Maintenance & Field Service

The portability and test capabilities of the Model 2635 make it particularly well suited for:

• Aircraft and aerospace maintenance
• Flight-line troubleshooting
• Maintenance facilities and repair depots
• Fabrication and production support
• Facilities with limited space
• Field service applications
• Vehicle and equipment electrical troubleshooting
