Expand globally with a competitive edge in the programmable logic controller (PLC) industry

The safety standard used for programmable logic controllers has changed from UL 508 to UL 61010-1 and UL 61010-2-201. With combined testing of PLCs, UL can speed up your time to market by bundling certifications for UL, CSA and IEC standards through a single trusted certification body. This streamlined and accelerated process saves time and money through a well-proven global certification program.
