WS0-XTIO safety input/output combined module

Safety-related parameters
This information relates to an ambient temperature of +40 °C, which is normally
used for the statistical calculation of the values.
Safety Integrity Level
SIL claim limit
Category *1
For single channel outputs with
test pulses enabled for all safe
outputs (Q1...Q4)
For single channel outputs with
test pulses disabled for this or
any other safe output (Q1...Q4)
For dual channel outputs with or
without test pulses disabled for
this or any other safe output
(Q1...Q4)
Performance Level
PFHd (mean probability of a
dangerous failure per hour)
For single channel outputs
For dual channel outputs
T (mission time)
M
*1 Applies for single channel outputs and for dual channel outputs.
*2 If safe outputs are used without test pulses, at least once per year either all safe outputs without test
pulses have to be switched off at the same time for at least 1 second or alternatively a power reset
has to be performed.
