Reference to earth ZP: connect ZP to several connectors. In the example, ZP is
connected to connector X3.
Characteristics of the analog inputs:
● The 8 analog inputs are not electrically isolated. The internal PTC connection is connected
to earth ZP (existing device: earth M). Depending on sensor type or measuring principle,
this may result in wiring adjustments.
● Resolution:
– Range 0 ... 10 V: 12 bit
– Range -10 ... +10 V: 12 bit + sign
– Range 0 ... 20 mA: 12 bit
– Range 4 ... 20 mA: 12 bit
– Range RTD (Pt100, PT1000, Ni1000): 0.1 °C
Connection examples for analog transmitters are shown below.
