Functional Performance Specifications
These BAYLOR SCR spare parts deliver industry-leading electrical reliability: OEM DC sensing boards (D28337-1/D28337-2) provide ±0.5% voltage/current measurement accuracy for precise SCR power regulation; hard firing PCB assemblies (28308) ensure stable thyristor triggering at 800mA rated current, eliminating SCR misfiring; marine-grade cables offer 600V dielectric strength and 110°C temperature resistance, with a service life of 15,000+ operating hours in drilling mud/saltwater environments; Roxtax RM60 modules create IP66-rated cable seals to prevent dust/water ingress; and gas detection hardware maintains continuous hazardous gas monitoring with 0.1% sensitivity for rig safety compliance.
Structural & Material Features
- OEM Precision PCB Engineering: SCR control boards feature high-grade FR4 substrate and gold-plated contacts, ensuring stable electrical performance and resistance to vibration-induced solder failure on drilling rigs
- Heavy-Duty Cable Construction: Marine/industrial cables use oil-resistant rubber insulation, bare copper conductors, and armored shielding to withstand abrasion, drilling fluids, and extreme temperature fluctuations (-40°F to 110°C)
- Corrosion-Resistant Hardware: Brass locknuts and Roxtax sealing modules resist saltwater corrosion and rig chemical exposure, maintaining long-term structural integrity
- Modular Electrical Design: Pre-terminated cable assemblies and plug-and-play PCB modules reduce field repair time by 70%, minimizing non-productive rig downtime
- Safety-Centric Design: All electrical components meet flame-resistant and explosion-proof requirements for hazardous drilling rig environments, complying with API safety mandates
Applicable Operating Conditions
These spare parts are built for harsh onshore/offshore drilling environments, optimized for BAYLOR SCR SE569T-III PM ThyRig 3 control systems used in mobile land rigs, offshore jack-up rigs, and semi-submersible drilling units. They perform reliably in ambient temperatures ranging from -40°F to 122°F, resist exposure to drilling mud, saltwater, oil-based fluids, and rig vibration, and endure continuous 600V electrical loading. Components are suitable for classified hazardous locations and fully comply with IEEE, API, and IEC electrical safety standards for drilling equipment.
Maintenance & Service Recommendations
- Inspect SCR PCB assemblies (D28337 series, 28308) quarterly for corrosion, loose contacts, or component damage; test voltage/current sensing accuracy bi-monthly to maintain SCR performance
- Inspect power/control cable insulation monthly for cuts, abrasion, or degradation; replace damaged cables immediately to prevent electrical shorts and safety hazards
- Check Roxtax sealing modules and cable glands semi-annually for proper sealing; tighten brass locknuts to maintain IP66 ingress protection
- Calibrate gas detection system hardware annually to ensure accurate hazardous gas monitoring and compliance with rig safety regulations
- Perform full SCR control board functional testing every 12 months; replace aging PCB assemblies during scheduled rig maintenance to prevent catastrophic failure
- Stock critical high-wear parts (PCBs, marine cables, sealing modules, gas detector components) at recommended minimum levels to avoid unplanned SCR downtime

Field Failure Repair Case Studies
Case 1: SCR Voltage Sensing Board Failure
A drilling rig’s BAYLOR SE569T-III SCR system lost power regulation capability due to a faulty DC voltage/current sensing board (D28337-1). Installing the OEM replacement sensing board restored ±0.5% measurement accuracy, fixed SCR misfiring, and resumed normal drilling operations.
Case 2: Marine Cable Insulation Breakdown
Unarmored marine control cable (37-102-516) suffered insulation breakdown from drilling mud abrasion, causing electrical intermittent faults. Replacing the damaged marine cable with OEM-spec 12AWG 3-conductor cable eliminated shorts and stabilized SCR control signals.
Case 3: Roxtax Cable Seal Leakage
Water ingress through a worn Roxtax RM60 sealing module caused corrosion in the SCR control panel junction box. Swapping in the OEM Roxtax multi-diameter module restored IP66 sealing, prevented further corrosion, and protected critical SCR electronics.
