tiastar smart MCCs

tiastar smart motor control center offering includes state-of-the-art motor control technology components and features that offer optimal motor control, protection, power monitoring, communications, and automation interfacing. 


Siemens smart MCCs are networked, NEMA compliant motor control centers that can communicate. They incorporate intelligent devices at the unit level to control and monitor motor operation, energy consumption, and power quality. Smart MCCs rapidly communicate with PLCs or process control systems via a data network.


Smart MCCs are internally interconnected using communication protocol, which incorporates intelligent devices such as SIMOCODE pro motor management systems, SIRIUS 3RW44 soft starters, SIMATIC PLCs, Siemens VFDs, and other smart components.
