1oo1 evaluation1oo1 evaluation
-> 1oo1 evaluation
Type of -> sensor evaluation – with the 1oo1 evaluation -> sensor is non-redundant and
connected to the F-module via one channel.

1oo2 evaluation1oo2 evaluation
-> 1oo2 evaluation
Type of -> sensor evaluation - 1oo2 evaluation covers two input channels which are
interconnected either with a single dual-channel sensor, or with two single-channel sensors.
The input signals are compared internally for equivalence or nonequivalence.

Acknowledgment time
The -> F-I/O acknowledges the sign of life specified by the -> F-CPU within the
acknowledgment time. The acknowledgment time is included in the calculation of the overall
> monitoring time and -> response time for the F-system.
Actuator
Actuators can be power relays or contactors for switching on loads, or they can be loads
themselves (e.g. directly controlled solenoid valves).
AUX1 bus
Power modules allow the additional connection of a voltage (24 VDC) which you can wire via
the AUX(iliary) bus. AUX(iliary) buses can be used individually as a protective conductor bus
or to supply additionally-required voltage.
