5.9 Connecting sensors to analog inputs
Introduction
The analog input modules support various sensors, such as voltage/current sensors, and
resistors, depending on the set measuring method.
This section contains general information that is generally applicable to all the connection
options for sensors described in the sections that follow.
Cables for analog signals
Always use shielded twisted-pair cables to wire analog signals. This reduces interference.
Connect both ends of the analog cable shield to ground.
If there are potential differences between the cable ends, an equipotential bonding current,
which can flow over the shield, can cause interference of the analog signals. To avoid this
situation, you should ground the shield only at one end of the cable.
Non-isolated analog input modules
In the case of the non-isolated analog input modules there is an electrical connection
between the reference point of the measuring circuit M
ANA
and chassis ground.
You use non-isolated analog modules if there are few or no potential differences between
the measuring sensors and chassis ground.
Isolated analog input modules
With the isolated analog input modules there is no electrical connection between the
reference point of the measuring circuit M
ANA
and chassis ground.
You use isolated analog input modules if a potential difference U
ISO
can occur between the
reference point of the measuring circuit M
ANA
and chassis ground. By means of an
equipotential bonding conductor between the M
ANA
terminal and chassis ground, make sure
that U
ISO
does not exceed the permitted value.
Limited potential difference U
CM
Only a limited potential difference U
CM
(common mode voltage) may occur amongst the M-
measuring lines of the input channels and between the leads and the reference point of the
measuring circuit M
ANA
. In order to prevent the permissible value from being exceeded, you
must take different actions, described below, depending on the potential connection of the
sensors.
