1. Product Overview

2. Electrical & Interface Specifications

• Dual-end fixed connectors: one side proprietary SUN SCSI male plug for WEStation onboard mainboard SCSI port; opposite end customized 25PIN serial plug matching PCB port of SUNMD/SUNID trackball 3A98826 full range.

• Double-shielded construction: inner twisted paired signal wire wrapped with aluminum foil + outer braided copper shielding, robust anti-EMI/RFI interference against cabinet power supply, relay and field analog signal noise in central control room environment.

• Operating parameter: rated signal voltage DC5V, impedance calibrated for Westinghouse dedicated SUN serial-SCSI hybrid bus; withstand AC500V insulation test, conform to industrial low-frequency signal transmission standard.

• Core difference vs H01: H01=standard short fixed length for built-in console internal wiring; H03=medium longer fixed length for remote panel mounting or separated desk layout routing.

3. Mechanical & Environmental Features

• Outer sheath: industrial black flexible anti-aging PVC jacket, oil-proof, abrasion resistant for long-term 24/7 continuous cabinet wiring service.

• Molded strain relief terminals at both plug ends to avoid internal conductor breakage caused by repeated plug/unplug during field maintenance.

• Ambient rating: Operating temp: 0℃ ~ +55℃; Storage temp: -40℃ ~ +85℃; Relative humidity 5%~95% non-condensing, compliant with CE industrial wiring component norms.

Full 3A98833 Series Length Classification

• 3A98833H01: Short standard length (integral inside single control cabinet)

• 3A98833H03: Medium extended length (separated desk nearby routing)

• 3A98833H12 / H23: Extra long customized length (cross-cabinet long-distance wiring)

4. Application Function

1. Exclusive transmission line transferring trackball cursor coordinate & left/right switch trigger signals between workstation main control board and embedded panel trackball, enabling WDPF HMI screen cursor control for valve/pump/equipment selection.

2. Matches WEStation original membrane keyboard to complete DCS parameter modification, alarm reset, picture page switch and control logic download in thermal & nuclear power plant central control system.

3. Essential replacement spare during WEStation cabinet retrofitting, trackball upgrade and old WDPF system fault overhaul projects.
