●
LEDs for display of status and
diagnostics
●
Electronics galvanically isolated
from the field level via opto couplers
●
2 analogue inputs for Pt100, Pt200,
Pt500 and Pt1000 as well as for
Ni100 and Ni1000
Function principle
BL67 electronic modules are plugged into
the purely passive base modules which are
needed for connection of field devices.
Maintenance is significantly facilitated due
to separation of the connection level from
the module electronics. Flexibility is enhan-
ced because the base modules provide a
choice of various connection technologies.
The electronic modules are completely in-
dependent of the type of higher level field
bus through the use of gateways.
