Smart motorstarter, for Modbus
UG 9411

The smart motorstarter UG 9411 can be used for softstart, softstop, reversing and protecting 1 phase asynchronous motors. By measuring the line current a thermal model is used to calculate the motor temperature, and in the case of overtemperature the motor is disconnected. In addition also a thermo switch can be used. The reversing is done via relays. The relays are switched without current flow, this provides long service life.
