Description

1. Product Introduction

Part No：3A98658H08｜Brand：Westinghouse / Emerson Automation
Product Type：WDPF System Custom Power Interconnect Cable / Rack Internal Wiring Harness, Revision H08
Belongs to classic Westinghouse WDPF DCS control system, exclusively matched for WEStation workstation rack & cluster TAP cabinet (same series as 3A98648G32 communication panel). Original OEM production permanently discontinued; available stock includes tested refurbished units, surplus original used spare for thermal power & petrochemical DCS field maintenance replacement.

2. Core Technical Parameter

  • Rated Voltage: DC +5V/+12V/-12V (VME backplane power transmission)

  • Conductor Spec: Multi-core shielded industrial copper cable, anti-interference shielding layer, compliant with WDPF internal power wiring standard

  • Connector: Custom molded dedicated plug for WDPF rack backplane & TAP panel terminal, H08 version optimized connector anti-loose structure

  • Working Ambient: Operating Temp 0℃~+55℃; Storage Temp -40℃~+85℃, RH 5%~95% non-condensing

  • EMC Grade: Meet CE & UL industrial control anti-surge & ESD standard, ±15kV contact ESD protection for cable terminal

3. Main Function

  1. Internal power distribution between WDPF cabinet backplane and 3A986XX series TAP communication panels, transmit multi-group DC power supply from rack power unit to onboard modules.

  2. Auxiliary signal interconnection for partial RTP bus low-speed signal transmission inside cluster cabinet.

  3. H08 upgraded revision improves bending fatigue resistance & high-temperature ageing performance vs earlier H-series versions, reduce loose contact failure under long-term cabinet vibration.

4. Application Range

Special supporting wiring accessory for Westinghouse WDPF DCS system, widely equipped in coal-fired power plant, cogeneration plant, petrochemical refining DCS WEStation control cabinet & network cluster rack, matching the full set of 3A986XX series communication assemblies.

5. Supply & Service Status

Emerson stopped new original production; commercial supply: refurbished tested spare, original dismantled used part with factory functional test certification, global maintenance repair available (standard repair cycle: 2–4 weeks, rush repair optional) with warranty coverage.
