AUMA SA 10.1 - Modbus Interface

The reversing contactors are designed for a lifetime of 2 million starts.1)
For the assignment of AUMA power classes, please refer to electrical data on actuator.2)
Not possible in combination with PTC tripping device3)
During an adjustable period (factory setting 10 seconds), faults in the supply voltage (e.g. voltage drops) will not lead to a fault signal.4)
Requires position transmitter in actuator5)
Requires position transmitter in actuator6)
Requires position transmitter in actuator7)
Further options for version with potentiometer or RWG in the actuator
Start and end of stepping mode as well as ON and OFF time (1 up to 300 seconds) can be
programmed individually for the directions OPEN and CLOSE.
