27.3 wiring
Two analog inputs can be wired to connector X1. A measuring range of 4–
20 mA with cable break monitoring is supported, as is a measuring range of
0–20 mA without cable break monitoring.
The current input channels use a differential voltage measurement at an
internal module resistor with a resistance of 50
Ω
.
It must be ensured that the input signals' voltage levels fall within the per-
missible common mode range.
