RS485-Fieldbus-Interface
The terminals of the RS485 fieldbus interface are called B'+ and A'-.
B'+ indicates the non-inverted bus line and
A'- indicates the inverted bus line.
The interface is electrically isolated.
The interface is equipped with "failsafe bias" resistors.
Note !
Bus cables, including shielded ones, must be laid at a sufficient distance from live
cables so that the signals are not affected.
