h
Time between the recognition of the signal change and the effective evaluation of an input signal. As a result,
multiple and short signal changes due to contact bounce of the components are not taken into account.

Contact function test
)
Note!
Make sure that an internal contact function test is carried out at the safe
inputs:
Safe input in the ON state
ƒ
A LOW level at one channel puts the input in the OFF state. The discrepancy
monitoring starts simultaneously.
ƒ
A LOW level must be detected at both channels within the discrepancy time,
otherwise a discrepancy error will be reported.
ƒ
To be able to acknowledge the discrepancy error, a LOW level must be
detected before at both channels.
Safe input in the OFF state
ƒ
A HIGH level at one channel starts the discrepancy monitoring.
ƒ
A HIGH level must be detected at both channels within the discrepancy
time, otherwise a discrepancy error will be reported.
ƒ
To be able to acknowledge the discrepancy error, a HIGH level must be
detected before at both channels.
