Safety PLCs
The offer introduces five new references - two CPUs and three I/O modules - and
also uses power supply module 140 CPS 124 20.
These products are certified for use in safety applications up to and including SIL2:
Safety CPU
Hot Standby safety CPU
Safety discrete inputs
Safety discrete outputs
Safety analog inputs
Power supply
(1) Product version (PV) = 3 (minimum).
The safety loop into which the Quantum Safety PLC is integrated consists of the
following 3 parts:

As far as SIL2 applications are concerned, standard IEC 61508 defines the
probability of failure on demand (PFD) or the probability of failure per hour (PFH),
depending on the system's mode of operation.

The Quantum Safety PLC has been certified for use with both low and high-demand
systems.
In terms of calculating the PFD/PFH values for a typical system, the maximum
permissible value for the PLC is 15%. The PFD/PFH values for the Quantum Safety
modules are listed in the table below for PTI values (see below) of 5 and 10 years:
