What EAC Delivers
EAC helps solve controls problems, improve reliability, modernize legacy systems and move automation projects from diagnosis through field execution.
01 / CONTROLS
Allen-Bradley ControlLogix / CompactLogix, Studio 5000, logic modifications, troubleshooting and operator-interface improvements.
02 / MODERNIZATION
Brownfield controls modifications, legacy modernization, system upgrades and staged migration planning with production realities in mind.
03 / TROUBLESHOOTING
Root-cause analysis for recurring controls faults, hard-to-diagnose downtime, poor diagnostics and production issues that keep returning.
Field-Oriented Engineering
Controls work is only successful when the complete system behaves correctly in production. EAC connects software decisions to field devices, electrical systems, operators and commissioning realities.

Why EAC
Elwell Automation Consulting LLC is a Washington-based industrial controls and automation engineering company founded by Brandon Elwell.
EAC combines controls depth with a maintenance and reliability perspective: understand how the equipment actually behaves, identify the technical cause and carry the solution through validation.
Project discussions stay close to the people responsible for engineering decisions and execution.
Solutions account for maintenance, diagnostics, commissioning and production realities.
From targeted troubleshooting to defined project scopes and longer-term engineering support.
PLC, SCADA, integration, commissioning and troubleshooting are core capabilities.
Engineering Capacity
EAC also provides technically screened controls engineers to support integrators, engineering firms and industrial project teams.
