ABB CB801 3BSE042245R1 PROFIBUS‑DP Communication Module

ABB CB801 (Part No.3BSE042245R1) is a PROFIBUS‑DP slave communication interface module for ABB AC800M and S800 I/O automation system. It acts as a bus gateway, realizing high‑speed data interaction between local I/O stations and upper‑level PROFIBUS‑DP master controllers.

This module adopts 9‑pin D‑Sub connector, supports auto‑baud‑rate detection and electrical isolation design. It supports periodic process data and non‑periodic parameter transmission, widely used as spare parts for energy, petrochemical and manufacturing automation cabinet maintenance and retrofit projects.
