4.4 Connection Variants
This chapter describes the correct wiring of the module in safety-related applications. The
connection variants specified here are permitted.
i
The contact makers must be connected to a resistor combination, e.g., 1 kW and 10 kW, to
detect open-circuits and short-circuits, see also Chapters
3.4.1 and 3.5.
4.4.1 Wiring with Proximity Switch or Wired Contact Maker
The inputs are wired via connector boards. Special connector boards are available for
redundantly wiring the modules.
The proximity switch supplies are decoupled using diodes. This ensures that the proximity
switch supplies of two modules can supply one proximity switch if the modules are
redundant to one another.
Connector boards X-CB 005 01 (with screw terminals) or X-CB 005 03 (with cable plug) can
be used to perform the wiring such as described in
Figure 13.
