Only use shielded cables for cable lengths > 30 m.
1)
Measuring range (-20 … 20 or 4 … 20) can be set using a pa‐
rameter. With a measuring range 4 … 20, the minimum value
monitoring (wire break) is automatically active.
2)
Only possible with a measuring range 4 … 20
3)
Monitoring switched off at approx. ±35 mA
4)
In the case of input currents greater than the maximum value,
an error is signaled and the input is switched at high resistance

Applies to: Optional I/O extension DA (X38)
6)
Applies to: Control sections with extended scope CSx02.1B
(X35), CDB02.1B (X36)
