Power module for Zone 1
Series 9445/32
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 chapter 6.2.

X1 Auxiliary Power Connection
To connect the auxiliary power using a 24 V auxiliary power set (item no. 261232 or 272278),
see chapter 6.3.
5.2
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/full redundancy. Power redundancy is always possible,
regardless of the communication protocol.
The following table shows the components required for the respective redundancy concepts:
Comply with the specifications for selecting the suitable 9496/32 socket and maximum
equipping of the 9442/32 CPU module and 9445/32 power module!
