The TURCK BL ident System
Characteristics and fields of application of the BL ident system
In order to comply with the demands presented by different fields of
application, TURCK offers the BL ident system with a whole range
of combination possibilities of data carriers and read-write heads as
well as interfaces for integration into fieldbus systems (e.g.
PROFIBUS-DP). Software modules enable simple integration and
commissioning.
The characteristics of the TURCK BL ident system are listed in the
following:
Degree of protection
All data carriers as well as the suitable write-read heads feature a
high mechanical degree of protection (e.g. IP67) and can thus be
subject to the most harsh industrial conditions.
The integration into a fieldbus system is implemented with suitable
TURCK interface modules. The interface modules are available in
degrees of protection IP20 and IP67. TURCK connection cables
featuring an adequate degree of protection round off the
identification system.
Service life
The service life results from the possible number or read-write
operations on the data memory.
FRAM memory features an unlimited number of read operations
and 10
10
write operations.
EEPROM memory features an unlimited number of read operations
and 10
5
write operations.
The data carrier does not require batteries.
Transmission frequency
The TURCK BL ident system operates with 13.56 MHz transmission
frequency between the data memories and the read/write devices.
Systems which operate with these transmission frequencies are
practically immune to electromagnetic interference. The 13.56 MHz
transmission frequency has developed into a standard in many RFID
fields of application.
