Terminals
The plug-in terminals for the inputs and outputs are not supplied with the system. You can
select between spring-loaded terminals and a screw connection.
Order details can be found in the catalogue or in the oeprating manual for the respective
unit.

Connecting safety inputs and outputs
In safety-related applications, it is essential that short circuits and open circuits are unable
to cause a hazardous condition within the plant.
The way in which this is done will depend on the degree of hazard from the plant section,
the switching frequency of the sensors and the level of safety of the sensors and actuators.
These points must be assessed in conjunction with the certification body responsible for
safety (e.g. BG, TÜV).
Depending on the application area and its respective regulations, the units can be used up
to SIL CL 3 of EN 62061 and up to PL e (Cat 4) of ISO 13849-1.
Various tests can be configured for safety inputs and outputs. These tests can be used to
detect many short circuits and open circuits. Examples of such tests are:
