1. Product Overview

3A98807G05 is dedicated 25-pin male DB25 serial communication cable of Westinghouse classic WDPF DCS system, belonging to 3A98807 series hardwire link harness, different from previous 3A9876X fiber optic series. It is customized RS232/DPU interconnection cable for WEStation operator workstation, DPU controller cabinet and local auxiliary control rack inside thermal & nuclear power plant control room. Original Emerson stopped new production; available stock includes factory-tested refurbished cable and original dismantled spare parts for legacy WDPF unit overhaul replacement.

2. Technical Specification

2.1 Electrical Parameter

  • Interface: One end fixed DB25 Male 25pin plug, standard full 25-core internal wiring complying with WDPF proprietary serial communication definition

  • Communication protocol: Matches WDPF internal RS232 serial bus, baud rate fixed for WEStation-DPU data handshake

  • Rated voltage: 0–24VDC signal circuit, anti-surge inner shielding wire restrains cabinet EMI interference from power modules and contactors

  • Insulation resistance ≥100MΩ, withstand voltage 500VAC/1min without breakdown

2.2 Mechanical & Environmental Parameter

  • Inner structure: Multi-core twisted pair with overall aluminum foil shielding + braided copper screen for anti-electromagnetic crosstalk

  • Outer sheath: Black flexible flame retardant PVC jacket, soft for dense cabinet internal wiring layout

  • Working temperature: 0℃ ~ +55℃ (installed condition); storage: -40℃ ~ +85℃, humidity 5%~95%RH non-condensing

  • G05 version feature: Optimized plug injection molding, built-in rubber dustproof ring at DB25 connector to avoid dust & moisture erosion inside cabinet, upgraded wire core tensile strength vs G01~G04 predecessor versions

3. Core Function

Establish hardwire serial communication channel between WDPF WEStation operation monitor station and central DPU controller:
  1. Upload real-time field process data, analog/digital acquisition signals from DPU to operator workstation

  2. Download human-machine control command, parameter setting and logic modification from WEStation down to DPU main control card

  3. Transmit system fault alarm, equipment self-diagnosis abnormal information bidirectionally; backup communication path when Westnet optical fiber bus fails temporarily

4. Application & Supply Info

Exclusive matching spare cable for Westinghouse WDPF DCS used in coal-fired power, cogeneration and nuclear power station control system renovation & daily maintenance.
  • Supply form: Tested refurbished finished cable / original used dismantled spare with quality inspection report

  • Standard delivery leadtime: 2~4 weeks, urgent expedited shipment available

  • Global delivery via DHL/UPS/FedEx with product warranty included
