Beyond the panel

Modernize the system without losing sight of production.

Whether the need is a new motor control platform, a targeted controls retrofit, better operational data, or support during startup, SSAC can address the complete automation lifecycle.

Industrial IoT & Operational Data

Connect legacy and modern equipment, monitor performance in real time, and create a more useful path from machine signals to maintenance and production decisions.

Hardware & Software Retrofits

Retain equipment that still performs while upgrading the controls, interfaces, communications, and software needed to improve reliability and extend service life.

Field, Startup & Technical Support

On-site troubleshooting, startup assistance, system validation, and ongoing technical support when equipment performance and production schedules are on the line.

HMI Enclosures & Screen Design

Custom operator interfaces, object libraries, alarm-management structures, enclosure integration, and screen mounting aligned to the operating environment.

Project credibility

Cutting MCC delivery time by 50 weeks with Rittal.

Watch SSAC explain the engineering and delivery approach behind an MCC project using Rittal and RiLineX—an example of how modular design, platform selection, and controls integration can change the project schedule.

Best-fit opportunities

Bring SSAC in when the controls scope affects uptime.

The strongest RFQs identify the equipment, operating problem, technical standard, schedule, and production constraint—not just a list of components.

01

New MCC or MC-PLEX System

Motor and VFD control, distribution, protection, networking, HMI, and system visibility in one coordinated project.

02

Custom Control Panel Build

PLC racks, I/O, enclosures, hazardous-location requirements, switchboards, and engineered panel assemblies.

03

PLC / HMI / SCADA Modernization

Replace outdated controls, improve operator visibility, integrate networks, and reduce dependence on unsupported hardware.

04

Startup, Retrofit or Field Support

Troubleshoot operating problems, validate system performance, commission upgrades, and protect the production schedule.
