External Control
Connections
Data of the external control connection boards of the ACx 600 product
family are given below.
ACS/ACC 600
NIOC-01 Board
Analog Inputs
The advantage of
the differential
analog input is that
the ground potential
of the device or
transmitter sending
an analog signal
can differ up to ± 15
V from the ground
potential of the
ACx 600 chassis
without disturbing
the signal.
Differential input
also efficiently
attenuates common
mode disturbances
coupled to control
cables.
