Function description 4- ][Funktionsbeschreibung Module Supply
Module supply
 The module supply provides the module with voltage.
][Funktionsbeschreibung Signale am Ausgang
Signals at the output
 “0” signal (0 V) at the output:
– Output is high impedance
– No current to the load
 “1” signal (+24 V) at the output:
– Output is low impedance
– Current is supplied to the load
][Funktionsbeschreibung_Peri Ausgang
Periphery supply
 The module routes the periphery supply from the module bus to the
base module terminals.
 The periphery supply is used to supply the outputs.
][Funktionsbeschreibung_Aus ST
Outputs
 The head module sets the output status via the module bus.
4.1.2 Integrated protection mechanisms
Integrated protection mechanisms 4- ][Schutzmechanismen E/A-Module
When the PSSu E F PS1(-T) is used to supply the system, the module
supply is buffered for 20 ms if the supply voltage is interrupted.
][Schutzmechanismen ST-Module
The module detects the following errors:
 Start-up error
 Configuration error
 ST communication error
 Bus termination error
