1.3 Field of application of the product
Only use the PSRmodular system in accordance with the area of application described in
this section.
1.3.1 Intended use
Use the safety modules and safe extension modules of the PSRmodular system only in ac-
cordance with the information provided in this section.
PSRmodular system The intended use for the PSRmodular system is safe switch-off. Safe switch-on does not
fall under the intended use.
All modules of the PSRmodular system are intended for use in industrial applications.
The safety modules and safe extension modules can only perform their safety-related tasks
if they have been integrated into the execution process in a correct and failsafe manner.
You must observe all information in this user manual as well as the user manuals and help
listed in section “Documentation” on page 16.
Only use the modules of the PSRmodular system in accordance with the specified technical
data.
For further information on using the PSRmodular system, please refer to “Using the system”
on page 23.
PSR-M-B1 and PSR-M-B2
base modules
The PSR-M-B1 and PSR-M-B2 base modules are configurable safety modules with safe in-
puts and safe outputs. The inputs are used to evaluate safety-related signal generators,
such as emergency stop buttons or safety doors. Circuits are interrupted safely via the out-
puts. Signal and clock outputs are also available.
You can connect a gateway for bidirectional communication to both safety modules.
