RIGHILL RP 126 Ground Fault PCB
RIGHILL RP 126 Ground Fault PCB is an industrial electronic circuit board intended for ground-fault monitoring and control functions in compatible feeder panels and SCR electrical systems. This board is primarily offered as a replacement or maintenance component for equipment in which the original installed PCB is identified as RIGHILL RP 126.
Ground-fault monitoring is an important function in industrial electrical installations because an unintended electrical connection between an energized circuit and ground may indicate insulation deterioration, damaged wiring, component failure or another abnormal electrical condition. The exact monitoring logic and response of this PCB depend on the original panel design, wiring diagram and board revision.
Ground-Fault Monitoring for Industrial Panels
The RIGHILL RP 126 Ground Fault PCB is designed to operate as part of a compatible electrical control and monitoring system. It may receive signals from the panel’s ground-fault detection circuit and process those signals according to the original system design.
Depending on the feeder or SCR panel configuration, the PCB may interface with indicators, alarms, relays, control circuits or other electronic modules. However, the precise inputs, outputs, trip settings and operating sequence must be confirmed using the original panel schematic or manufacturer documentation.
This product should not be selected only because it is described as a ground-fault PCB. Different boards can perform similar general functions while using different supply voltages, connectors, signal ranges, calibration settings and output arrangements.
RIGHILL RP 126 PCB for Feeder Panels
In a compatible feeder panel, the RIGHILL RP 126 Ground Fault PCB can form part of the protection or fault-indication circuit associated with the electrical feeder. Feeder panels distribute electrical power to downstream circuits and equipment, making the correct identification of abnormal ground conditions important for safe operation and maintenance.
When replacing an existing feeder-panel board, technicians should compare the full model designation, connector arrangement, terminal identification, component layout and revision markings. The associated current transformers, sensing circuits, relays and indication devices should also be checked according to the panel drawings.
Application in SCR Control Systems
The RIGHILL RP 126 Ground Fault PCB is also specified for compatible SCR panel applications. SCR systems are commonly used for controlled power conversion and motor-control duties in industrial and drilling-rig electrical installations.
Within an SCR system, a ground-fault board may support the monitoring of abnormal leakage or grounding conditions in the associated power and control circuits. The exact monitored section may vary according to the design of the SCR lineup, feeder arrangement and connected equipment.
Because SCR systems can contain high-energy AC and DC circuits, replacement and testing of this PCB should only be carried out by personnel familiar with the applicable panel, isolation procedures and electrical drawings.
Replacement of the RIGHILL RP 126 Ground Fault PCB
The RIGHILL RP 126 Ground Fault PCB should be ordered using the complete model reference shown on the original circuit board. Before ordering, inspect both sides of the existing PCB for model numbers, assembly numbers, serial numbers, revision letters, calibration labels and connector identification.
A board with the same basic model number but a different revision may include changes to component values, connector pin assignments, operating thresholds or panel compatibility. For this reason, clear photographs of the front, rear, connectors and identification labels are recommended when requesting a replacement.
The condition of the complete panel should also be evaluated before replacing the PCB. A failed board may sometimes be the result of another fault, such as an incorrect supply voltage, damaged wiring, moisture, excessive heat, contamination, a defective sensing device or a short circuit in the connected equipment.

Important Compatibility Checks
Compatibility must be verified before the RIGHILL RP 126 Ground Fault PCB is installed. The board model alone may not provide enough information to guarantee correct operation.
- Confirm the manufacturer name and complete model number.
- Check the PCB assembly number and revision code.
- Compare all plug, socket and terminal positions.
- Verify the board supply voltage from the panel schematic.
- Confirm the input signals and output connections.
- Inspect the component and jumper configuration.
- Check calibration labels and adjustable settings.
- Verify compatibility with the feeder or SCR panel model.
Installation and Safety
Installation of the RIGHILL RP 126 Ground Fault PCB should be performed by qualified electrical or electronic maintenance personnel. The feeder panel or SCR system must be properly isolated, locked out and verified as de-energized before the board is removed or installed.
Electrostatic-discharge precautions should be used when handling the PCB. Avoid touching conductive tracks, connector pins and electronic components unnecessarily. Inspect the replacement board for transportation damage, loose components, corrosion or contaminated connectors before installation.
After installation, all connectors should be checked carefully before power is restored. Functional testing should follow the original equipment procedure. Protective circuits must not be bypassed merely to clear an alarm or return the equipment to service.
Ordering Information
Before ordering the RIGHILL RP 126 Ground Fault PCB, provide the full identification details visible on the existing board. Where possible, include photographs of the complete PCB, model label, revision marking, connectors and the associated feeder or SCR panel nameplate.
Electrical specifications such as supply voltage, sensing range, alarm threshold, relay rating, dimensions and connector pinout were not included in the supplied product information and should not be assumed. These details must be verified against the original board, panel schematic or manufacturer documentation.
