Components Function Diagram
Shielding bracket The shielding bracket is an insertable bracket for modules with
EMC-critical signals (e.g., analog modules, technology modules), and
(together with the shielding clamp) permits the low impedance
application of shielding with minimal installation times.
The shielding bracket is included in the scope of delivery of the analog
and technology modules, and may be ordered as an accessory
(Page 193).
Shield clamp The shield clamps are used to attach cable shielding to the shielding
bracket.
The shield clamp is included in the scope of delivery of the analog and
technology modules, and may be ordered as an accessory
(Page 193).
Power supply element The power supply element is inserted in the front cable connector, and
serves to supply power to modules with EMC-critical signals (analog
modules, technology modules).
The power supply element (connection technology: screw terminal) is
included in the scope of delivery of the analog and technology
modules, and may be ordered as an accessory (Page 193).
Labeling strips for the
exterior of the front
cover of the
I/O modules
Labeling strips can be inserted for the system-specific labeling of
modules. The labeling strips can be printed, and are available in
various colors.
The labeling strips are included in the scope of delivery of the
I/O modules. Additional labeling strips may be ordered as Accessories
(Page 193).
4-pole connection plug
for supply voltage of
the CPU
In the delivery condition of each CPU a 4-pole connection plug is
plugged on the CPU.
Load current supply
(PM)
A load current supply supplies the S7-1500 automation system
through a front connector of the CPU. A load current supply does not
occupy a slot in the configuration and is not included in the system
diagnostics.
If you are using load current supplies, we recommend the devices
from our SIMATIC series. These devices can be mounted on the
mounting rail.
The load current supply can be planned using STEP 7.
Load current supplies are available in various models:
• PM 70W 120/230V AC
• PM 190W 120/230V AC
