NOTICE
Electronics modules include electrostatically sensitive devices. Incorrect handling can cause damage
to the electronics modules.
• Observe the handling specifications for electrostatically sensitive devices.
• Discharge static electricity from your body before assembling or disassembling modules to protect
the modules.

Intended use
The input module CPX-F8DE-P is intended for reliable recording and evaluation of signals of connected
sensors.
The input module provides up to eight secure inputs that can be used by a higher-order safety
controller in a safety function. The communication with the higher-level safety control is implemented
by the secure PROFIsafe protocol via a PROFIBUS or PROFINET IO fieldbus connection.
The inputs on the input module can be combined for multi-channel sensor applications. Two inputs
combined form a channel pair, which is set separately with one of 11 function modes. The function
modes influence the evaluation of the input signals and optionally the generation of clock signals.
The characteristics of the inputs comply with the IEC 61131-2 standard for Type 2 digital inputs.
The input module CPX-F8DE-P is a product with safety-relevant functions. The input module is
intended for installation in machines or automation-technology systems and may be used only as
follows:
–
in excellent technical condition
–
in its original condition, without unauthorised modifications
–
exclusively in the configurations specified in this description
2.3.3 Details of the function modes
–
within the limits of the product defined by the technical data
–
in an industrial environment.
NOTICE
• Note that the safety engineering system limits of the product are also its physical limits.
The user is responsible for use of the input module in a safety function.
