Wiring diagram
For non-intrusive version with MWG within actuator
Setting of limit and torque switching via local controls
Via fieldbus interface
Galvanically isolated analogue output 0/4 – 20 mA (load max. 500
Ω
). Option, only possible in combin-
ation with output contacts.
Torque feedback signal
Settings/programming the Modbus RTU interface
Baud rate, parity and Modbus address are set via the display of actuator controls
Setting the Modbus RTU interface
General data of the Modbus RTU interface
Modbus RTU according to IEC 61158 and IEC 61784
Communication protocol
●
Line (fieldbus) structure. When using repeaters, tree structures can also be implemented.
●
Coupling and uncoupling of devices during operation without affecting other devices is possible.
