Features of ABB TP851 3BSE01811BR1

Fast, Bumpless Switch-over: Designed for critical process control applications, the TP851 enables extremely fast and "bumpless" (seamless) transfer of control from the primary to the backup CPU in the event of a fault.

Fault Tolerance: By allowing redundant CPUs, the TP851 module eliminates a single point of failure at the controller level. If one CPU experiences an issue, the backup takes over, maintaining fault-tolerant operation and significantly increasing the reliability and uptime of the entire industrial automation system.

High Integrity / Safety Certification Contribution: The TP851 is essential for control systems that require high Safety Integrity Levels (SIL), such as SIL3 certification (IEC 61508).

Integrated Baseplate/Interconnection: It functions as an integral baseplate or adapter that the redundant CPU modules plug into within the controller unit. It provides the necessary electrical and mechanical connections, as well as the underlying logic for redundancy management, directly on the controller backplane.

More Description

Function: The TP851 is a baseplate designed to house and connect a communication interface module, specifically the CI851.
Purpose: It acts as a mechanical and electrical interface, enabling the CI851 module to connect to the CEX-Bus (Controller Extension Bus) within ABB's AC 800M controller systems.
Power: It receives power from the processor unit via the CEX-Bus, meaning it doesn't require a separate external power source.
CI851: This is the core component that provides Profibus-DP communication capabilities. Profibus-DP (Decentralized Peripherals) is a widely used fieldbus standard for industrial automation, allowing communication between control systems (like ABB's AC 800M) and distributed I/O devices or other field devices.
