INDUSTRIAL CONTROL FIELD

Industrial Applications

VOOHU supplies the Ethernet ports, serial isolation, power magnetics and port protection used at every level of an industrial control system. The architecture below runs from servo drives, VFDs, sensors and instruments at the field level, through PLCs, motion controllers and remote I/O, over industrial Ethernet (such as PROFINET and EtherCAT) and fieldbus into HMIs, industrial PCs, industrial switches and edge gateways, and up to MES / SCADA and enterprise cloud platforms.
