The temperature sensor connections determine which inputs will be used. Up to four
different RTD sensors of type Pt100, Pt1000, or Ni1000 with an individual temperature
range can be connected to each EASY-E4-DC-4PE1(P) expansion device.
Inputs that do not have a sensor connected to them will be "undefined."
By default, all inputs will be undefined and accordingly will be switched off.
The temperature ranges for the EASY-E4-DC-4PE1(P) depend on the selected sensor.
