Hi,

Is it necessary to have SICAM PS in SICAM RTU 400 station? Is it possible to have usually PS, which takes only two slots in rack instead SICAM PS which takes 3 slots in rack?

Does anybody know anything about it?

Hi Dugme,

I always used "normals(not SICAM package)" PS of 10Aand 20A and I never had problems.

Do you use a RTU Station or a Simatic 400 Station with DI, CR, AI, MCP modules of SICAM.

Hi,

In the manaul of Sicam don't comment about differences between PS of SICAM and SIMATIC, only there a possibility of PS-SICAM with 48 and 60Vdc.

But, doesn't forget that:
The SICAM RTU must not be equipped with more than one CPU, which must be plugged into slot 4 of the central rack.

Ok.

In this case, there are not problems in using a PS of 2 slots and the CPU in the slot 3.
