1. Product Introduction

Full 3A98833 Length Gradation Summary

• 3A98833H01：Short standard, single cabinet internal wiring

• 3A98833H03：Medium length, adjacent desk short routing

• 3A98833H12：Extra-long, cross nearby cabinets wiring

• 3A98833H23：Ultra-long customized factory length, multi-cabinet / separated remote operator desk layout

2. Electrical & Interface Parameters

• Two fixed molded terminals: One proprietary SUN SCSI male plug for WEStation onboard mainboard dedicated SCSI port; opposite customized 25PIN dedicated serial plug fully compatible with all 3A98826 SUNMD/SUNID trackball PCB ports.

• Premium double-layer full shielding: Twisted-pair signal core + inner aluminum foil wrap + outer dense braided copper shield, specially optimized for ultra-long distance anti-EMI/RFI, effectively suppress cabinet power supply, relay, field analog signal interference in long-span wiring scenarios.

• Electrical rating: DC5V signal working voltage, impedance fine-calibrated for Westinghouse exclusive SUN hybrid SCSI-serial bus; passed AC500V withstand insulation test, meets industrial low-speed precision signal transmission criteria.

• Special upgrade vs shorter models: Optimized conductor wire gauge to reduce long-distance signal attenuation, avoid cursor drift/button malfunction under ultra-long wiring installation.

3. Mechanical & Environmental Features

• Outer jacket: Black industrial anti-aging flexible PVC sheath, oil-proof, abrasion-resistant, flame retardant for 24h continuous long-term control cabinet operation.

• Integral injection molded strain relief at both plug ends, prevents inner core wire breakage from bending, pulling or repeated plugging during on-site overhaul.

• Working ambient: Operating temperature 0℃~+55℃; storage temp -40℃~+85℃; RH 5%~95% non-condensing, compliant with CE industrial control component standard.

4. Application Scope

1. Transmit trackball X/Y coordinate signal + left/right click trigger signal between WEStation host and remote separated trackball panel, realize WDPF HMI screen cursor control for pump/valve equipment selection, parameter setup & alarm acknowledgement.

2. Matches original WEStation membrane keyboard to complete DCS picture switching, logic download, process parameter modification in thermal/nuclear power plant central control system.

3. Core spare for old WDPF system upgrade, remote operator console reconstruction, cross-cabinet workstation relocation project.
