4.4 Connection
Variants
This chapter describes the correct wiring of the module in safety-related applications. The
connection variants specified here are permitted.
4.4.1 Input
Wiring
The inputs are wired via connector boards. Special connector boards are available for
redundantly wiring the modules.
The transmitter supplies are decoupled using diodes. This ensures that the transmitter
supplies of two modules can supply one transmitter if the modules are redundant to one
another.
Connector boards X-CB 008 51 and X-CB 019 51 (with screw terminals) or X-CB 008 53
and X-CB 019 53 (with cable plug) can be used to perform the wiring such as described in
Figure 13 and Figure 14.
