■

The power module PM-E DC 24 V is used within an ET 200pro 

station when generating 24 V DC load voltage groups for elec-

tronics modules. 
You can position power modules in an ET 200pro station any-

where to the right of the interface module. The first power mod-

ule is already integrated in the interface module. 
Each power module which you install in the ET 200pro station in-

terrupts the load voltage busbar, and opens up a new potential 

group (common potential) for the load voltage supply 2L+. All 

subsequent load voltages of the electronics modules are fed 

from this power module. Each power module has a replaceable 

fuse for protecting the device. Only line protection according to 

DIN VDE 0100 need be provided externally in addition. 
The electronics/sensor supply 1L+ is not interrupted by the 

power module, it is looped through.
The power module is fitted on the associated bus module when 

delivered.

For detailed technical specifications of the power module PM-E, 

see:
• Catalog IK PI
• Mall/CA 01 under "Distributed I/Os / ET 200pro"

B) Subject to export regulations: AL: N, ECCN: EAR99H

■

The connection module for the power module PM-E is used to 

connect the load voltage 2L+. It is fitted on the power module. 
The module must be ordered separately, and is available with 

the following types of connection:
• CM PM-E direct 
• CM PM-E ECOFAST
• CM PM-E 7/8"
