Connecting Up - Siemens SIMATIC ET 200SP Manual

Properties
● BaseUnit suitable for all I/O modules of the BaseUnit type "A0/A1". Can be recognized by
the laser inscription on the front and/or the last two digits of the article number.
– Supply voltage (L+ terminal, ground): Max. 24 V DC/10 A
– Current-carrying capacity per process terminal (terminal 1 to 16): Max. 2 A
● The BaseUnit opens up a new potential group. The self-assembling voltage buses P1 and
P2, and the AUX busbar are interrupted to the left-hand neighboring module (BaseUnit,
interface module).
● Access to the AUX busbar via terminals
● 16 terminals to the process (assignment through the I/O module)
● 10 AUX terminals for connecting a protective conductor or potential. The AUX busbar is
not connected to the I/O module. Max. 24 V DC/10 A
● Connection system in the form of push-in terminals Connection cross-sections are
available in the ET 200SP System Manual
(https://support.industry.siemens.com/cs/ww/de/view/58649293).
Maximum configuration per potential group
The number of I/O modules that can be used per potential group depends on the following
factors:
1. Total power requirement of all I/O modules operated on this potential group
2. Total power requirement of all loads connected externally to this potential group
The total current calculated according to item 1. and item 2. must not exceed 10 A.
