Overview

The Honeywell TK-PRR021 is a Redundancy Module designed to provide fault-tolerant operation in Honeywell’s TDC 3000 and Experion PKS control systems.

It ensures continuous system availability by supporting redundant configurations of controllers and communication paths. In the event of a hardware or communication failure, the module automatically switches to the backup path, thereby minimizing downtime and maintaining process safety.

Technical Data

Typical Applications

The TK-PRR021 module is widely deployed in industries requiring high system availability and fault tolerance:
