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-Ausgang Relais
The module has the following protection mechanisms:
 Safe separation between both relay contacts (see Technical details)
 Safe separation between both relay contacts and the periphery sup-
ply as well as the module supply, in accordance with DIN VDE 0110
overvoltage category 2 in a protected industrial network
 Temperature monitoring
The module provides the following diagnostic data:
 Start-up error
 Configuration error
 ST communication error
 Bus termination error
 Temperature error: too warm
 Temperature error: too hot

Module supply
 The module supply provides the module with voltage.
][Funktionsbeschreibung_Aus Relais
Outputs
 The head module sets the output status via the module bus.
][Funktionsbeschreibung Derating  The relationship between the load current and the operating temper-
ature is illustrated in the following derating diagram. The operating
point should be below the characteristic curve.
