GE 336A4937RDG004 PAC Power Wire Assembly

Configured for power distribution and signal transmission in GE Mark Ve Gas Turbine Control Systems, the GE 336A4937RDG004 (336A4937RDG004 PAC Power Wire Assembly) provides direct physical/electrical execution. The wire sub-assembly routes localized control loop current and logic power lines natively at the hardware tier to interconnect internal power backplanes and card racks.

Hardware Specifications

Industrial Control & Drives Backplane Infrastructure

• I/O Density Scaling and Control Core Distribution The 4-inch assembly establishes a dedicated point-to-point connection within the controller rack framework to handle low-voltage power distribution. This physical harness layout enables tight module grouping and supports high I/O density scaling by routing core power tracks around confined chassis paths without causing mechanical binding or limiting airflow.
• Profinet / EtherNet/IP and Deterministic Logic Coexistence The heavy-gauge 20 AWG conductor geometry is engineered to reduce internal line impedance and minimize high-frequency noise emissions from the switching bus. This reduction in electromagnetic cross-talk allows the power distribution assembly to run close to communication links connected to Profinet / EtherNet/IP deterministic networks without causing data packet corruption or signal reflection anomalies.

Frequently Asked Questions

Q: How does the PAC Power-JPDL insulation layer perform under sustained heat exposure inside turbine enclosures?

A: The JPDL insulation consists of a high-temperature dielectric compound rated to withstand a continuous operational envelope from -40 to +70 deg C. The polymer jacket resists chemical breaking, embrittlement, and thermal outgassing when mounted inside unventilated control cabinets exposed to ambient turbine deck radiant heat.

Q: Can this 20 AWG wire assembly be fieldsman-altered or spliced to increase the 4-inch length?

A: No, modification of the pre-fabricated 336A4937RDG004 wire assembly is not permitted. The harness features factory-crimped, low-resistance termination points calibrated to match standard Mark V power board receptacles; field splices degrade signal parameters and compromise structural continuity under vibration.
