9.4 Mechanical and climatic ambient conditions
Operating conditions
The ET 200AL IO-Link I/O modules are intended for weather-proof, stationary use.
•
The operating conditions surpass the requirements of IEC 61131-2:
– Class OTH2
You can find the values for the operating conditions in the technical specifications of the
equipment manuals or on the Internet
