Hello All , 

I want to know what is the max. Temperature under which profibus cable can work .  This is an application of a Power plant one of the Steam Generation Section where the Temp goes 50-70⁰C. 

Thank You,

Vaibhs.

Hello,

probably this link can help you:

Yes it will work. Permitted ambient conditions = -40 deg cent to +75 deg centg

Please check this data sheet

PB FC STANDARD CABLE GP SOLD BY THE M

Hello,

The Siemens PROFIBUS cable is intended for fixed installation in buildings or in an environment which is protected from the climate (in-house cabling). The combination of twisted wires, foil shield and braid shield make the cable particularly suitable for industrial environments subject to electromagnetic interference. The design of the cable also guarantees stable electrical and mechanical characteristics after the cable has been installed.

Permitted ambient conditions:

Operating temperature – 40 °C + 60 °C

Transport/storage temperature – 40 °C + 60 °C

Installation temperature – 40 °C + 60 °C

 Hello,

You can find the Permitted ambient conditions of SIEMENS PB cable in the attached Picture

Also the whole datasheet is here

Thanks All,

 This is Really helpful

Hello,

Kindly find the attached file.

Hello, 

As friends told here that maximum temperature for Profibus cable is 75 degree.  And as you told that temperature can reach to 70 degree. 

I do recommend not to work with profibus copper solution.  Because any overheating may affect on the communication. 

My suggestion is to go for FO solution.  You will need two OLM and fibre optic cable to link in between. 

Hope this helps.

Here is the permitted temperature range for the FO cables:
