TB850 | 0 °C to +60 °C | flexible multi-protocol Ethernet communication module

Description

Product Overview

The ABB TB850 is a powerful and flexible multi-protocol Ethernet communication module for the high-performance AC 800M and AC 800M High Integrity (HI) controller families. Engineered as a primary network interface, it provides robust, high-speed connectivity for the controller to participate in modern, Ethernet-based plant networks and safety systems. The ABB TB850 supports a range of critical industrial protocols concurrently, including PROFINET IO Controller/Device, EtherNet/IP Scanner/Adapter, and Modbus TCP Client/Server, enabling seamless multi-vendor integration. With features like MRP (Media Redundancy Protocol) for resilient network topologies and integrated switch functionality for easy device daisy-chaining, it is designed for demanding applications requiring high availability and deterministic data exchange.
