Communication via the
PSR TBUS DIN rail
connector
The PSR-TRISAFE-S safety module is equipped with an interface for the PSR TBUS DIN
rail connector. The PSR DIN rail connector from Phoenix Contact can be used to connect
slave extension modules. Communication with these modules is then established
automatically via the connector on the PSR DIN rail connector. Safety-related cross-wiring
is not required (see also "Mounting the safety module" on page 3-13).
