3D04109G01

3D04109G01 is a WDPF SBX 351/51 I/O module manufactured by Westinghouse (now Emerson) for the legacy WDPF DCS platform. It serves as a core input/output unit for process control, enabling data acquisition and control signal output in industrial automation systems.

Description

Specifications

  • Manufacturer: Westinghouse (Emerson)

  • Model: 3D04109G01

  • Type: WDPF SBX 351/51 I/O Module

  • Compatible System: WDPF DCS

  • Function: Industrial process input/output control

  • Mounting: Standard WDPF SBX rack mounting

  • Application: Power plants, petrochemical, water treatment (legacy WDPF systems)

Key Features

  • Dedicated for WDPF DCS: Designed as a native I/O module for Westinghouse’s legacy distributed control system.

  • Rugged Industrial Design: Built for 24/7 continuous operation in high-noise, harsh industrial environments.

  • Integrated I/O Interface: Provides multiple channels for analog/digital input and output, supporting field sensor and actuator connections.

  • Easy Integration: Seamlessly installs into WDPF SBX racks, compatible with existing system backplanes and power supplies.

  • Legacy System Support: Critical spare part for maintenance and retrofit of aging WDPF installations.

Applications

  • Power Generation: Monitoring and control of boiler, turbine, and auxiliary systems in thermal power plants.

  • Petrochemical Plants: Process control for refining, chemical synthesis, and pipeline operations.

  • Water/Wastewater Treatment: Automation of pumping, filtration, and chemical dosing processes.

  • Legacy System Retrofits: Replacement I/O module for extending the service life of existing WDPF DCS.

Related Part Numbers

  • 3D04106G Series: Fiber optic repeaters for WDPF/Ovation (e.g., 3D04106G07).

  • WDPF SBX Series: Other I/O modules, power supplies, and communication boards for the WDPF platform.

Notes

This is a legacy component for the WDPF DCS, no longer in active production but widely available as new surplus, refurbished, or used parts for system maintenance. It is not compatible with Emerson’s modern Ovation DCS without adapters.
Need me to list the main differences between 3D04109G01 and the earlier 3D04106G series?
