Our company has manufactured custom and standard control panels since 1985. From conceptual design to finished product, Sigma Controls can handle the smallest to the largest control panel project. Utilizing our own microprocessor based controller (Myriad Series) any industrial programmable controller (PLC) or simple relay logic, a control panel can be fabricated to meet the specific job requirements. All Sigma control panels are designed to meet all applicable national and local standards NEC, FPA, and NEMA. We are a UL508A certified facility and we can certify any panel as a listed, serialized UL assembly.
