BL67 components
2.2.2 Electronic modules
The standard electronics modules contain the I/O-functions of the BL67 modules (power distribution
modules, digital and analog input/output modules, and technology modules).
They are plugged onto the base modules and are not directly connected to the wiring and can be
plugged or pulled when the station is being commissioned or for maintenance purposes, without
having to disconnect the field wiring from the base modules.
Power Feeding-modules
Power Feeding modules distribute the required 24 V DC field voltage to the I/O-modules. They are
necessary for building groups of modules with different potentials within a BL67 station, or if the rated
supply voltage for the outputs cannot be guaranteed.
Power Feeding modules are potentially isolated from the adjoining power supply module and the I/O-
modules to the left side.

Note
For detailed information about the individual BL67 I/O components, please refer to the
chapters 2 to 8 of the manual "BL67- I/O-modules" (TURCK Documentation-No.: German

D300572 ; English D300529 ).
The "Appendix" to the manual mentioned above contains (amongst others) a list of all BL67
components and the assignment of electronic modules to base modules.
