Diagnostic Function
Signaling device
errors and input
circuit monitoring /
shunt monitoring
a)
(P51*00) via analog
output signal
Signaling device
errors via binary
relay output
a) Rated current approx. 20 μA
b) The diagnostics output is protected against inverse polarity and short circuits up to 30 V DC.
The maximum permissible voltage across current/voltage output and diagnostics output is 50 V.
Unused terminals must be potential free.
