A Terminal side
B Sensor side
Fig.8-10: Connection of analog sensors in case of signal lines > 10 m
If you intend to use both channels of the terminal R-IB IL AI 2/SF,
you may connect the shield system in several ways, depending on
the line cross-section.
1. To connect the two sensors, you should use a multi-core line;
connect the shield via the shield connector, as described
above.
2. To connect the two sensors, a thin line should be used; con‐
nect the shield system for both lines via the shield connector.
Connecting Analog Output Terminal R-IB IL AO ...
● Connect the shield system via the shield connector (see Con‐
necting Lines to Tension Spring Connection Points page
62 ).
● Connect the shield system to the FE potential over an area as
large as possible.
Development of ground loops!
The shielding system may be connected directly to the ground po‐
tential at one point only.
●
If lines are more than 10 meters in length, they should always
be decoupled by means of an RC element (on the actuator
side).
The typical value of the capacitor C should range from 1 nF to 15 nF.
The value of resistor R should be at least 10 MΩ.
