Mechanical and Climatic Environmental Conditions
Mechanical Environmental Conditions
The mechanical environmental conditions for the fail-safe I/O module are listed in
the following table as sinusoidal oscillations.
Frequency Range
(Hz)
10 ≤ f ≤ 58
58 ≤ f ≤ 150
Reduction of Vibration
If the fail-safe I/O module is subjected to greater shock pulses or oscillation, you
must take appropriate measures to reduce acceleration and amplitude.
We recommend that you mount the ET 200eco on cushioning material (for
example, on a rubber-metal vibration damper).
