Connecting - Siemens SIMATIC ET 200SP Manual

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.
– 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 further conducts the potential group. The self-assembling voltage buses P1
and P2, and the AUX bus are connected to the left-hand neighboring module (BaseUnit).
● 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 Connection cross-sections are
available in the ET 200SP System Manual
