2. Installation2.4 Connection terminals2.4.4 Connecting analog inputsOnly possible on base devices.Base devices with DC and UC voltage can read analog voltages within a range of 0 to10 V via inputs I5, I6, I7, and I8 on the EASY-E4-... base device.The signal has a 12 bit resolution, value range 0 - 4 095.The following applies:l I5 = IA01l I6 = IA02l I7 = IA03l I8 = IA04The analog voltage inputs can also be used as digital inputs.Figure 16: Connecting analog inputsSETPOINT encoder:Use a potentiometer with a resistance ≤ 1 kΩ, e.g., 1 kΩ, 0.25 W.DANGERAnalog signals are more sensitive to interference than digital signals.Consequently, greater care must be taken when laying and connectingthe signal lines. The measures described below must be adhered to inorder to prevent any deviations in analog values. An incorrect con-nection can lead to unwanted switching states.52 easyE4 11/18 MN050009 EN www.eaton.com
