Description
Product Overview
The Emerson Bristol Babcock 396879-11-0 is the main processing module for a ControlWave Micro remote automation controller. In remote monitoring and control applications, the CPU executes programmed logic, processes field data, and manages communications with supervisory systems and connected equipment. Typical application environments include pipeline stations, pumping facilities, water and wastewater infrastructure, and distributed industrial process sites.
Published specifications identify a 150 MHz processor and 16 MB of flash memory. A procurement specification published by Bharat Petroleum also lists 64 MB SDRAM, two Ethernet interfaces, one RS-232 interface, and one RS-485 interface for this part number. Other catalog listings differ on serial-interface details, so confirm the actual hardware revision and port layout before specifying communication cables or planning a replacement.
The module is listed as a replacement for 396879-01-2, but buyers should confirm the replacement relationship against the installed controller’s hardware and software configuration. A CPU replacement can affect application execution, communications, configuration retention, and the recovery process following installation. Before removing the existing module, back up the application and configuration where possible, document network settings, and establish a tested recovery procedure. Because this is a legacy ControlWave Micro component, confirm availability, revision, and testing evidence rather than assuming that an item advertised as new is current factory production.
Product Introduction
The Emerson Bristol Babcock 396879-11-0 ControlWave Micro CPU module supports controller processing and communications in remote automation installations. It is intended for compatible ControlWave Micro hardware rather than as a standalone general-purpose computer.
For maintenance teams, the essential checks are the full part number, controller model, communication-port arrangement, firmware and application compatibility, and backup availability. Verify the power-input requirements from the controller documentation and installed hardware label before energizing a replacement.
