High current flowing through the voltage jumpers UM and US leads to a temperature rise of the voltage
jumpers and the inside of the terminal. Note the following instructions to keep the current flowing
through the voltage jumpers of the analog terminals as low as possible:
All of the analog terminals need a separate main circuit.
If this is not possible in your application and if you are using analog terminals in a main
circuit together with other terminals, place the analog terminals behind all the other
terminals at the end of the main circuit.

Connection Notes
Do not connect voltages above ±5 V to a current input. The electronics module will be
damaged if the maximum permissible current of ±100 mA is exceeded.
Always connect analog sensors using twisted and shielded cables (see Figure 5).
m
Connect the shielding of the terminal using the shield connector clamp. The clamp
connects the shield with high resistance and capacitance to FE on the module side.
Additional wiring is not necessary.
s.
co
When connecting the sensor shielding with the PE potential, ensure a large surface
connection.
nt
Within the terminal, ground is connected to FE via an RC element.

If you want to use both channels of the IB IL 24 AI 2/SF-230 terminal, you can connect
the shield in various ways depending on the cable feed.
1
If one multi-wire cable is used to connect both sensors, connect the shielding as described above
using the shield connector (see Figure 5).
6
6232A
IB IL 24 AI 2/SF-230
If two individual cables are used to connect the sensors, proceed as follows to prevent ground
loops (see Figure 6):
Install a busbar with a connection to the ground potential in front of the Inline terminal (B in
Figure 6). Place the outer sheath of the two cables in the appropriate position and connect
the shields of both cables, e.g., using an SK shield clamp (see "CLIPLINE" Catalog). The
busbar must be the only point at which the shield of every cable is connected with ground
potential.
•
Lead the cables to the Inline terminal and connect the shield, as described above, using the
shield connector (A in Figure 6).
•
Lead the sensor cable into the sensor making sure to maintain the integrity of the cable
insulation (C in Figure 6).

possible:
You cannot change the signal input

measurement is selected by applying
the measured signal to the current or

preset configuration is accepted and the first
measured value is available. If you change the
configuration the corresponding channel is reinitialized. The message "Measured value

process data output words for 100 ms

Electrical Isolation/Isolation of the Voltage Areas
m
To provide electrical isolation between the logic level and the I/O area it is necessary to
supply the bus terminal and the sensors, which are connected to the anaolg input terminal
described in this data sheet, from separate power supplies. Interconnection of the 24 V
power supplies is not permitted.
