NEW 6ES7193-6BP20-0BF0

Model and Series Identification: This product, designated 6ES7193-6BP20-0BF0, is part of the SIMATIC ET 200SP system’s base unit family, specifically classified as a “BaseUnit BU20-P16+A2” with specialized features. It serves as the mechanical and electrical interface between ET 200SP signal modules and the system’s backplane bus, facilitating power distribution and data communication in modular automation setups.

Core Function: Its primary role is to provide a secure mounting platform for ET 200SP signal modules (such as digital I/O, analog I/O, or specialty modules) while establishing essential electrical connections. It enables power supply to connected modules and supports data transmission between the modules and the central controller via the ET 200SP backplane bus, ensuring seamless operation in distributed automation environments.

Mechanical Specifications: The base unit features a compact 20mm width, optimized for space-efficient installation in control cabinets. It is designed for DIN rail mounting (compatible with standard 35mm DIN rails) and includes a robust locking mechanism to secure attached signal modules, preventing accidental disconnection in industrial settings. It accommodates 16-pin front connectors for field wiring, simplifying installation, maintenance, and module replacement.

Electrical Characteristics: It distributes 24V DC power to connected signal modules and supports communication through the system’s backplane bus. The base unit incorporates reverse polarity protection to safeguard against wiring errors, enhancing system reliability. It provides galvanic isolation between field circuits and the backplane bus, minimizing the impact of electrical noise and interference in harsh industrial environments.

Compatibility and Integration: Specifically engineered for use with SIMATIC ET 200SP signal modules, it supports a wide range of I/O modules to meet diverse automation needs. It integrates seamlessly into ET 200SP stations, enabling connection to central controllers (e.g., S7-1200, S7-1500) via PROFINET or PROFIBUS. The base unit supports hot swapping of modules when used in appropriate configurations, allowing for module replacement without system shutdown, thus reducing operational downtime.

Protection and Environmental Features: The base unit has an IP20 protection rating for the backplane area and IP40 protection for the front connector area when properly mated, making it suitable for control cabinet installation. It operates reliably within a temperature range of -25°C to 60°C (storage temperature: -40°C to 70°C) and is built to withstand industrial levels of vibration and shock, ensuring durability in demanding environments.

Compliance: It adheres to international standards such as IEC 61131-2 and RoHS directives, ensuring compatibility with global industrial requirements and environmental regulations.
