Flameproof enclosure
When routing the cable between
the transducer, controller and
power supply, avoid proximity to
high voltage lines to prevent noise
coupling. Especially critical is in-
ductive noise caused by AC har-
monics (e.g. from phase-control
devices), against which the cable
shield provides only limited protec-
tion.
Position information is sent over the
RS 485/422 interface as synchro-
nous serial data (SSI) to the host
controller. High noise immunity is
assured by the differential drivers
used for sending and receiving sig-
nals.
Cable length max. 400 m. The
clock frequency is a function of the
cable length:
Cable length Clock frequency
< 25 m < 1000 kHz
< 50 m < 500 kHz
< 100 m < 400 kHz
< 200 m < 200 kHz
< 400 m < 100 kHz
