Easy. Multi-functional. Safe.

Compared to conventional motor starters, the EMS2 makes it much easier and faster to implement applications with safe stop in accordance with SIL 3 and PLe. The multi-functional design makes it easier to set up the main/control circuits, thereby reducing the number of hardware components by 70 %.

SmartWire-DT – added value for your entire machine

The SmartWire-DT system replaces the conventional control wiring of switchgear with a communications-enabled plug-in connection. This in turn reduces the time required for wiring, testing and commissioning to a minimum.

Motor starter feeder system – simple, flexible and safe

With the optional EMS-X accessory, the EMS2 electronic motor starter can be easily integrated into the feeder system without using any tools. As the plug-in technology automatically establishes an electrical and mechanical connection to the feeder module, the motor starter is immediately ready for use.
