Technical Description: 6ES7138-6AA01-0BA0
The Siemens 6ES7138-6AA01-0BA0 is a **BaseUnit (Type A0)** for the SIMATIC ET 200SP distributed I/O system. It serves as the physical mounting rack and electrical connection point for the peripheral I/O modules.
Key Features
- Type: BU15-P16+A0+2D.
- Terminals: Push-in terminals (16 process terminals).
- AUX Terminals: Yes (for PE connection or voltage distribution).
- Color Code: Light-colored (Opens a new potential group).
Functionality
This light-colored BaseUnit is critical because it separates the power groups on the backplane bus. It feeds the 24V DC supply to the modules plugged into it and passes it on to the dark-colored BaseUnits on its right. The «Push-in» technology allows for tool-free wiring, reducing installation time by up to 50% compared to screw terminals.
Compatibility
Compatible with all standard ET 200SP I/O modules requiring a 15mm width BaseUnit. Essential for assembling a new IO station.
