The TK-PRR021 is a high-integrity redundancy interface designed for the Honeywell Experion PKS Series C platform. This module provides a dedicated high-speed synchronization link between primary and backup C300 controllers, ensuring “bumpless” failover in mission-critical applications. In the event of a primary controller failure, the TK-PRR021 enables the secondary processor to seamlessly take over without interrupting the process or losing data.
Utilizing a high-bandwidth proprietary protocol, this module continuously mirrors controller memory, database states, and I/O status, delivering real-time fault detection and immediate failover. Designed for industrial environments, the TK-PRR021 features robust galvanic isolation, onboard LED diagnostics, and plug-in installation for Series C chassis, making it a cornerstone for fault-tolerant Distributed Control System (DCS) architectures.

Fault-Tolerant DCS Architectures: Supporting redundant C300 controller pairs for critical process loops.
Process Continuity: Ensuring zero-downtime operations in high-stakes facilities such as oil & gas, chemical, and power plants.
High-Availability Networks: Synchronizing state and memory across distributed control nodes within a plant network.
Q: How does the TK-PRR021 manage failover?
A: The module maintains a continuous heartbeat and memory mirror between primary and secondary C300 controllers. If the primary fails, the secondary is signaled to take over in milliseconds, ensuring uninterrupted process control.
Q: Does this module require a separate power supply?
A: No, the TK-PRR021 draws its operational power directly from the Honeywell Series C backplane.
