Component Function Image
Interface module ...is plugged onto the terminal module. The interface
module connects the station to the CPU of the automa‐
tion system and prepares the data for the assembled
electronic modules.
Note IM 152-1PN:
A media converter is required to connect the IM 152-1PN
interface module to a CPU. The media converter converts
PROFINET IO into an intrinsically safe optical signal. The
optical transceiver on the media converter or on the
switch must be approved for ATEX/IECEx Zone 1/21.
Note IM 152-1DP:
When you operate the distributed I/O in a hazardous area
of Zone 1, you need an RS 485-IS coupler.
Note IM 152-1PN and IM 152-1DP:
The electronic modules are the same for both interface
modules.

Electronic module ... is plugged onto the terminal module and determines
the function:
• Digital electronic modules for NAMUR encoders, dig‐
ital output, relay module
• Analog electronic modules with current and resist‐
ance measurement circuit, thermoresistor and ther‐
mocouples, analog output
• Reserve module
• WATCHDOG module
Termination module ...terminates the station
Media converter with SFP trans‐
ceivers approved for ATEX/
IECEx Zone 1/21
... converts the PROFINET IO into an optical signal when
an IM 152-1PN is used.
