For more than 40 years, Systems Interface Inc. (SII) has delivered automation and control solutions that power critical industries, including aerospace, infrastructure, water and wastewater, food and beverage, marine, and material handling.

We are more than a systems integrator. We are engineers, problem solvers, and partners who bring complex ideas to life—whether that means modernizing a legacy control system, developing a new SCADA platform, or commissioning equipment in the field across the country.

From UL 508A and 698A panel fabrication to complete system integration, PLC and HMI programming, and field commissioning, every project we take on is designed, tested, and delivered with precision. Our in-house engineering and manufacturing teams work together to ensure every control panel, network, and automation system meets the highest standards of quality and reliability before it leaves our facility.

As a Rockwell Automation Gold System Integrator Partner, we combine deep technical expertise with hands-on field experience. We have supported major infrastructure projects such as the SR 520 Floating Bridge, provided advanced control systems for U.S. Coast Guard vessels, and delivered scalable automation for food production and industrial water treatment facilities across North America.

What sets us apart is not only our technical capability but also our commitment to doing things right. We collaborate closely with each client from concept to commissioning, creating solutions that fit their process, their people, and their goals.

At Systems Interface, our mission is simple:
To engineer automation that works—built to perform and built to last.
