2.4.9 Analog input expansion with temperature measuring

Temperature inputs cannot be used as digital inputs.
The EASY-E4-DC-4PE1(P) analog input expansion features four (4) analog RTD inputs
that can be used to integrate Pt100, Pt1000, or Ni1000 temperature sensors.
The Pt100, Pt1000, or Ni1000 inputs are suitable for 2-wire and 3-wire connections. In
addition, unshielded or shielded cables with a length of up 30 m can be used for the con-
nection. Finally, averaging for temperature readings can be set up.
When connecting temperature sensors, make sure to use the right configuration
depending on whether you are using a 2-wire or 3-wire connection. If the temperature
sensors are connected using a 2-wire connection, the corresponding input terminals
must be connected to each other, i.e., input terminals 2 and 3 for T1, input terminals 5
and 6 for T2, input terminals 8 and 9 for T3, and input terminals 11 and 12 for T4.
When inputs on an EASY-E4-DC-4PE1(P) are not used, all three input ter-
minals must be connected to each other.

DANGER
Analog signals are more sensitive to interference than digital signals,
therefore the signal cables should be carefully routed and connected.
An incorrect connection can lead to unwanted switching states.
Unshielded signal cables must be routed separately from AC cables.
In order to prevent fluctuating analog values, you should take the measures specified
for Engineering → Section "Analog Signals", page 40
easySoft 7 is required in order to be able to configure the connected RTD sensors.
