EMERSON 396879-11-0 Control Module

Emerson 396879-11-0 Control Module (Ovation / ControlWave System CPU or I/O Module)

 

The Emerson 396879-11-0 is a ControlWave / Ovation series industrial control module, commonly used as a PLC/RTU CPU or I/O controller module in power plant, turbine, and process automation systems.

 Important: Despite different listings calling it “input module” or “CPU module”, it is generally part of an Emerson ControlWave/Ovation distributed control system (DCS/RTU architecture) rather than a simple PLC plug-in card.

Key Specifications

• Model: 396879-11-0
• Brand: Emerson
• System Family: ControlWave / Ovation / RTU platform (varies by configuration)
• Product Type: CPU / Controller / I/O system module (system-dependent)
• Function:
  • Process control logic execution (RTU/PLC function)
  • Signal processing for field I/O
  • Communication with SCADA / DCS systems
• Power Supply: typically 10.7 – 30 V DC (source)
• Communication:
  • Serial (RS-232 / RS-485)
  • Ethernet (optional system configuration)
• Operating Temperature: industrial wide range (-40°C to +70°C typical)
• Mounting: rack / backplane system

What it actually does

This module is used in critical infrastructure control systems:

• Reads field signals (analog + digital I/O modules)
• Executes control logic (like PLC/RTU)
• Communicates with SCADA/DCS systems
• Controls:
  • turbine speed systems
  • generator sets
  • process plants

So it is part of a distributed control architecture, not a standalone controller.

Features & Advantages

• Industrial RTU / PLC-class control capability
• Designed for power plant & utility-grade systems
• Supports multiple communication protocols
• High reliability for 24/7 operation
• Modular expansion with I/O racks
• Suitable for remote automation sites (oil, gas, power)

Applications

• Power plants (gas / steam / hydro)
• Generator control systems
• Oil & gas pipeline automation
• Water treatment facilities
• Turbine and compressor control systems
• SCADA remote stations
