Properties
● BaseUnit suitable for all I/O modules of BaseUnit type "C0/C1". Can be recognized by the
laser inscription on the front and/or the last two digits of the article number.
– Supply voltage (terminal 1 L, 2 / 1 N, 2 N): Max. 230 V AC/10 A
– Current-carrying capacity per process terminal (terminal 1 to 4): Max. 5 A
– Current carrying capacity per process terminal (terminal 5 and 6): Max. 10 A
● The BaseUnit opens up a new potential group by means of the inserted I/O module. 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
● 6 terminals to the process (assignment with the I/O module)
● Two AUX terminals for connecting a PE terminal 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 You can find more information 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.
