1、 Basic Product Information
Project Description
Product model 6ES7972-0AC80-0XA0
Product Name: PROFIBUS Repeater Module
Belonging to Siemens SIMATIC S7 and SINEC L2 bus systems series
Manufacturer Siemens AG

2、 Core functions and features
PROFIBUS signal relay

Used to extend the physical distance of PROFIBUS-DP network;

Eliminate attenuation and interference through signal regeneration, shaping, and amplification.

Line segment isolation

Provide electrical isolation to prevent the spread of faults;

Each bus segment can work independently, facilitating fault diagnosis and maintenance.

Expand network structure

Support the construction of longer and more complex topology structures (such as star and tree);

Suitable for situations where multiple bus segments are connected in parallel.

Plug and play, no configuration required

No programming required, it works automatically after installation;

Equipped with LED indicator lights to display operational status and data transmission status.
