LOUISIANA ELECTRIC 170156 Digital DC Motor Field Supply Module 160095, 160102

Product Overview

The LOUISIANA ELECTRIC 170156 is a Digital DC Motor Field Supply Module associated with a dual-armature current tracking field supply control system. Available identification records describe it as a Digital DC Motor Field Supply / Field Supply Bridge, with Drawing No. STDFS502-6 and Size B.

The assembly includes several identified control and protection components, including a DV/DT PCB board and a Field Loss Relay Board. These subcomponents are identified by separate part numbers and revisions, so the complete assembly should be matched by the main 170156 part number as well as the installed board markings.

The 160095 and 160102 numbers identify individual boards within the documented assembly rather than alternative electrical ratings for the complete 170156 module. Current listings show slightly different recorded weights, so the actual shipping weight should be confirmed from the physical unit.

Component Identification

The available records are useful when checking an existing cabinet or replacement assembly:

170156 — Main digital DC motor field supply / field supply bridge assembly.

160095 — DV/DT PCB board, Revision 05.

160102 — Field Loss Relay Board, Revision 3.

160101 — Additional associated part number identified in the assembly documentation.

160089 — Also listed as a related part number on current marketplace records for the DUAL configuration.

This distinction is important when purchasing a replacement. A listing for 160095 or 160102 alone should not automatically be treated as a complete 170156 field supply assembly.

Application

The 170156 is intended for DC motor field-supply and field-control applications. Its documented dual-armature current tracking configuration makes it relevant to industrial motor-control equipment where field supply and field-loss monitoring are part of the control system.

Potential applications include:

DC motor control systems
Industrial drive equipment
Motor field excitation systems
Rig and heavy industrial machinery
Legacy DC drive installations
Motor protection and field-loss monitoring

The exact application should be confirmed against the original machine documentation because detailed electrical ratings for the complete 170156 assembly are not reliably published in the available records.

Installation & Configuration

Before replacing a 170156 assembly, record the complete identification from the existing unit. Check the main part number, drawing number, board revisions, terminal wiring, and installed subcomponents.

Particular attention should be paid to the 160095 DV/DT PCB and 160102 Field Loss Relay Board. Their revisions should be compared with the original assembly before installation.

Recommended replacement procedure:

Isolate and lock out the associated drive system.
Verify that the DC bus and motor field circuits are fully discharged.
Photograph existing wiring and terminal positions.
Record all board part numbers and revision markings.
Compare the replacement assembly with the original.
Check cooling and fan connections.
Verify field-supply wiring before energizing.
Perform controlled commissioning and monitor field current and protection signals.

Do not apply power based solely on the 170156 part number. The original machine wiring and field-supply ratings should always be verified.

Maintenance Recommendations

For older DC motor field-supply equipment, periodic inspection is particularly useful.

Check:

PCB condition and connector seating
DV/DT board for signs of overheating
Field-loss relay operation
Power terminals and cable connections
Cooling fan operation
Dust accumulation
Signs of heat damage or discoloration
Loose wiring or degraded insulation

The associated 190801 fan is identified as a 115 VAC, 50/60 Hz, approximately 20 W motor fan in the available assembly description.

If the module has been stored for an extended period, inspect electrolytic capacitors, connectors, insulation, and PCB surfaces before placing it back into service.

Replacement Notes

The complete designation 170156 should be used when searching for the field-supply assembly.

Searches using only 160095 or 160102 may return individual PCB assemblies instead of the complete field supply module. Current marketplace records also associate 160089 and 160101 with the DUAL 170156 configuration.

Because detailed electrical ratings for the complete assembly are not clearly documented in the available sources, voltage, current, and motor horsepower should be confirmed from the original equipment nameplate or machine drawings rather than inferred from the part number.
