Control Panels
We build low and medium voltage custom control panels. Types of panels include;
- Generator Controls
- Pump Controls
- Turbine Protection
- Air Compressor
- Data Center Controls
- Chemical Plant Controls
- Renewable Energy Controls

Panels are built to UL 508A and UL-listed if required. Panels are function tested prior to shipment. Depending on size and complexity of job onsite commissioning maybe performed.
Control Panel HMI Development
Our custom generator control panels or local control panels may include HMI touch displays. Panels may include HMI displays from Rockwell Automation Panelview Plus with RSView ME development suite or Schneider’s Magelis family with the Vijeo Designer.
The HMI touch panels vary in size from 5” to 18” depending on manufacturer and panel requirements.

PLC Programming
As part of the custom switchgear or control panel assembly, SAI will design, develop, and function test the PLC (programmable logic control) to supplied requirements and specifications. We specialize in the Allen-Bradley families of PLCs (ControlLogix, CompactLogix, MicroLogix, SLC, & PLC5), however other manufacturers’ controllers, such as GE, Siemens, Schneider, ComAp, Woodward, and Basler can be provided.
PLC Development
- Creating the ladder logic and native tags in the processor
- Wiring local and field devices to digital and/or analog I/O cards
- Communicating with various devices, such as engine modules, power monitors, and protective relays over different protocols, such as:
- Modbus
- Canbus
- CAT Data Link (CDL)
- Integration into SCADA / DCS systems, either in the native tag format of the processor, such as L5K, or via Modbus.
Our custom PLC solutions typically provide controls for gas or diesel engine-driven generators used for prime power or standby power. We provide controls for other engine driven applications including pumps and motors.
System management and monitoring is performed by local HMI, or remotely over VPN with web application access.
PLC Integration
Depending on the customer requirements; we can include standard, redundant or SIL2 rated PLC integration. We can provide PLC controls only or provide and integrate low or medium voltage switchgear as a turn-key system.
Retrofitting Panels
Retrofitting panels allows faulty or obsolete equipment to be replaced with new equipment.
A walk-though is typically performed in order to inventory equipment. Old equipment is usually sent to SAI for retrofitting. New equipment is installed, configured and tested prior to shipment. Panel are tied into existing operations and commissioned to verify functionality and integration of operations.
Retrofitting control panels is a cost-effective way to address aging, broken or unsupported equipment. New equipment delivers improved performance, new features like digital controls and modern communication protocols plus improved maintenance with active product support and warranty.
UL Standards and Certification
Our control panels are built to UL standards and are available with UL-listing upon request. For non-hazardous locations panels can be offered with UL/cUL 508A rev 3. For classified locations, we can UL-list per UL/cUL 1203 or 1604 for explosion-proof / hazardous location (HazLoc) CID1 or CID2.
- UL/CUL-508 (Industrial Control Panels)
- UL/CUL-1203 (Control Panels in Hazardous Locations - Class 1, Div 1, Groups B,C,D)
- UL/CUL-1604/ISA 12.12.01-2007 (Control Panels in Hazardous Locations - Class 1, Div 2, Groups A,B,C,D)
Experience
With over 40 years in business, we have built and commissioned hundreds of control panels and shipped them all over the world. Our panels are built to high standard with proven reliability.
We have seen and built panels of all types and sizes. We have expert level knowledge in a wide range of products, engine manufacturers and control equipment. We have developed a library of panel designs which enables quick RFQ turnaround.
Our history, reputation and strong relationships with vendors improves our purchasing power through priority access to products / components, reducing lead times and special pricing agreements.
