Siemens 6ES7193-6BP20-0DA0 ET 200SP series

Siemens 6ES7193-6BP20-0DA0 is a base unit in Siemens ET 200SP distributed I/O system, used to connect and power signal modules (SM), communication modules (CM) or process modules (PM). The following are its details:

I. Product positioning and core functions

Series: ET 200SP (modular, compact distributed I/O system, suitable for S7-1200/1500 PLC).

Function:

Mechanical support: As the physical carrier of the module, it provides a DIN rail installation interface.

Electrical connection: Data transmission between modules is realized through the backplane bus (P bus and K bus), and power is distributed to the modules.

Programming interface: Integrated PROFINET programming interface, supports direct connection to programming devices (such as PC) for module diagnosis or firmware update.

2. Key technical parameters

Parameters Details

Order number 6ES7193-6BP20-0DA0

Width 15mm (ultra-compact design, saving space in the control cabinet)

Power supply mode - Main power supply: powered by PM-E DC 24V module or adjacent basic unit

- Auxiliary power supply: optional (need to be matched with AUX terminal module)

Supported module types Digital/analog I/O modules, communication modules, process modules (such as counters, positioning modules)

Terminal type Spring-type terminals (tool-free, fast wiring, support 0.25-1.5mm² wire)

Programming interface - PROFINET RJ45 interface

- Support TIA Portal online diagnosis and firmware update

Protection level IP20 (need to be installed in the control cabinet)

Diagnostic function-LED status indication (power supply, bus communication, module fault)

- Support module hot swap (need to be powered off)

3. Typical application scenarios

High-density I/O expansion:

In a control cabinet with limited space, through multiple 15mm Wide base units are installed side by side to expand a large number of I/O modules (such as digital input/output, analog modules).

Distributed automation system:

As a remote I/O station, it is connected to the main controller (such as S7-1500 PLC) via PROFINET to achieve decentralized control.

Fast maintenance scenario:

Spring-type terminals support fast replacement of faulty modules to reduce downtime; the programming interface can directly diagnose the module online without dismantling the entire station.

Technology module integration:

Connect technology modules such as high-speed counters and positioning modules to achieve precise motion control or measurement functions.

IV. Comparison with other models

ET 200SP basic units have multiple models, the main differences are width, terminal type, programming interface and power grouping function:
