2.1 PSRmodular safety system: Structure and method
of operation
Overall system: hardware
and software
The PSRmodular safety system consists of the following components.
– PSR-M-B1 and/or PSR-M-B2 base modules
– Optional PSR-M-EF, PSR-M-EM, PSR-M-TBUS safe extension modules or PSR-M-E
standard extension modules
– PSRmodular Software for configuration
– Safe control devices, sensors, and actuators (depending on the application)
The diagram below illustrates the overall system in an application example with the
PSR-M-B1 or PSR-M-B2.
