Properties
● A combination of
– 15 mm BaseUnit of type A0, light-colored version without AUX terminals with article number 6ES7193-6BP00-0DA0
– 15 mm BaseUnit of type A0, dark-colored version without AUX terminals with article number 6ES7193-6BP00-0BA0
● 2x 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 light-colored side of the 2x BaseUnit opens 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).
● The dark-colored side of the 2x BaseUnit conducts the potential group. The self-assembling voltage buses P1 and P2
and the AUX busbar are connected to the light-colored side of the 2x BaseUnit.
● No access to the AUX bus via the terminals.
● 16 terminals to the process (assignment through the I/O module)
● 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/en/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.
