IS1+ power module for Zone 2 / Division 2
Series 9445/35
Project engineering specifications depending on the ambient temperature
Adjust mounting processes based on the maximum ambient temperature,
see the "Technical Data" chapter.
Updating/replacing modules
• Observe the "Replacing and upgrading the module" chapter.
5.1
Redundancy
The IS1+ Remote I/O system can also be implemented redundantly based on the
communication protocol. Here, a distinction is made between CPU redundancy,
power redundancy and system redundancy/full redundancy.
The following table shows the components required for the respective redundancy concepts:
*System redundancy/full redundancy in preparation
Comply with the specifications for selecting the suitable 9496/35 base and maximum
equipping of the 9442/35 CPU modules and 9445/35 power modules!
