2. Technical Introduction
A sudden processor failure, communication port dropout, or memory fault in a remote telemetry unit (RTU) can sever supervisory control links, leaving critical oil, gas, or water infrastructure running blind without remote oversight.
The Emerson / Bristol Babcock 396879-11-0 is a high-performance CPU module designed for the ControlWave Micro hybrid PLC/RTU platform. Featuring dual Ethernet ports, a robust 150 MHz processor, and 16 MB of Flash memory, it manages complex deterministic control logic, data logging, and redundant communication protocols across distributed field sites. Serving as an upgraded drop-in replacement for the older 396879-01-2 version, deploying a verified original module restores processing capability and network connectivity without rewriting application code.
Engineer’s Takeaway: Procuring an authentic Emerson 396879-11-0 ensures exact backplane pin compatibility, correct OpenBSI protocol handshakes, and strict thermal rating compliance, preventing unexpected configuration hurdles during remote panel upgrades.

4. Field Engineer’s Tech Notes
- IP Addressing and Configuration Backup: Prior to pulling a failing CPU card, use OpenBSI configuration software to extract the active network parameters, IP address configurations, and user programs. The replacement 396879-11-0 module must be re-initialized with the correct node ID and network settings before integration onto SCADA backbones.
- Firmware Version Alignment: Verify that the ControlWave firmware revision running on the local engineering workstation matches or supports the runtime image of the replacement CPU to avoid communication timeouts or protocol mismatches during project downloading.
5. Adaptive QA & Testing Protocol
Every unit undergoes rigorous bench validation prior to dispatch. For the Emerson ControlWave 396879-11-0, our technicians mount the module on a dedicated ControlWave Micro test rack to verify processor bootstrap execution, test dual Ethernet port communication speeds, validate serial port loopbacks, and check internal memory integrity under continuous power cycles. Functional test reports or pre-shipment video verification can be provided upon request.
6. Buyer’s FAQ
- Are these CPU modules supplied as New Surplus or factory fresh?
We stock both factory-sealed New Surplus (NSFP) and fully bench-tested, static-safe operational units. Condition status is explicitly marked on every quote.
- What warranty coverage comes with this part?
All replacement Emerson automation components are backed by a standard 12-month operational warranty from the date of invoice.
- How fast can this module ship to minimize system downtime?
In-stock items ship same-day via priority air courier services to global destinations, mitigating critical path delays during emergency site outages.
- Is the 396879-11-0 fully backward compatible with older ControlWave Micro racks?
Yes, this module is engineered as a direct hardware and functional replacement for the legacy 396879-01-2 version, slotting directly into existing backplanes without physical modification.
