2 Overview
2.1 Module structure
A module consists of
}Electronic module and
}Base module with
– Screw terminals or
– Cage clamp terminals
The base modules are the carrier units for the electronic modules and are used to connect
the field wiring. The electronic modules are inserted on to the base modules and determine
the module's function.
Details of the base modules that can be used are available in the chapter entitled “Intended
Use”.
2.2 Module features
The product has the following features:
}Infeed for periphery supply
}Infeed for C-rail supply
}Failsafe switching off of the periphery supply (block switching)
}LEDs for:
– Switch status of periphery supply
– Periphery supply
– Module error
}Application range depends on the base module
}T-type:
PSSu E F BSW-T: for increased environmental requirements

3.1 Intended use
The module meets the requirements of EN IEC 61508 up to SIL3 and EN954-1 up to Cat-
egory4.
The module may be used to switch off the periphery supply on standard modules.
}If the module is used to switch off standard output modules (e.g. PSSu ES 4DO0.5 or
PSSu ES 2DO2), Category3 of EN954-1 can be achieved.
}If the module is used to switch off modules of type PSSuEPD, Category4 of EN954-1
can be achieved.
The module may be used to switch:
}Resistive loads
}Inductive loads
The module PSSu E F BSW-T is suitable for use where there are increased environmental
requirements (see Technical Details).
Intended use includes making the electrical installation EMC-compliant. Please refer to the
guidelines stated in the "PSSuniversal Installation Manual". The module is designed for use
in an industrial environment. It is not suitable for use in a domestic environment, as this can
lead to interference.
