7 ifm Profibus DP modules
7.1 General technical information
ifm Profibus DP modules connect each I/O module directly to the Profibus� Thus, a
100% transparent transmission is ensured�
The module variety ranges from standardised digital industrial signals to analogue
input/output modules� For temperature monitoring, resistance temperature
detection modules are available� The compact robust housing with fully potted
electronics allows usage directly on the machine�
7.2 Supply voltage
The supply voltage is connected via 4-pole M8 connectors on each module�
7.2.1 Operating voltage
U
B
: 24 VDC (-15 %/+20 %)
The 24 VDC operating voltage U
B
is used to power the fieldbus (termination), the
processor logic, the inputs as well as the sensors�
The operating voltage is electrically isolated from the fieldbus (ASIC)�
7.2.2 Load voltage
U
L
: 24 VDC (-15 %/+20 %)
The load voltage U
L
powers the digital outputs� It can be fed separately� If the load
voltage is turned off (e�g� in an emergency-stop), both the fieldbus function and the
supply and the input function will be retained�
The modules are each equipped with a 4-pole M8 plug and a 4-pole M8 socket for
voltage supply�
