Function and device design
4.1
Function
Application range
The fieldbus isolating repeater 9185/11-35-10 is used to isolate an intrinsically safe RS-485 interface from
a non-intrinsically safe RS-232, RS-422 or RS-485. The device is suitable for the operation of intrinsically
safe PROFIBUS DP or Modbus RTU. Depending on the variant, the devices can isolate and/or convert
specific interfaces.
Variants
The fieldbus bridge 9185/1.-46-10 is used to separate the system interfaces from the field side interface
and links a PROFIBUS network to operating devices in the Exicom series.
Using galvanic isolation and the "bit refresh" function, the isolating repeater 9185/12-4.-10 ensures the
interference-free transmission of Profibus, Modbus and R. STAHL ServiceBus signals.
Mode of operation
The isolating repeater blocks any equalization currents and protects sensitive devices against transient
noise. The device supports both RS-485 and RS-422 systems. In addition, it can adapt RS-232 interfaces
to RS-485 or RS-422. This enables standard PCs to be connected to RS-485 or RS-422 interfaces.
Converting to RS-485 or RS-422 means that transmission systems connected to RS-232 can achieve
larger transmission distances.
