Product Overview

The Honeywell TK-PRR021 serves as the specialized high-availability backbone for the C200 controller family within the Experion PKS architecture. This 100% Brand New and Original redundancy module facilitates a fault-tolerant environment by executing real-time data mirroring and state synchronization between primary and secondary processors. By establishing a dedicated high-speed link, the TK-PRR021 guarantees a "bump-less" transfer of control. If the active processor encounters a hardware failure or power interruption, this module triggers an instantaneous failover, allowing the standby unit to assume full process control without dropping communication to field devices or interrupting critical batch operations.

Engineering Advantages

Deterministic Data Mirroring: The TK-PRR021 manages the continuous transfer of database and runtime parameters between the primary and secondary C300/C200 processors. This ensures the standby unit possesses an identical "process image," eliminating the need for manual data reloading during an emergency switchover.
Bump-less Failover Capability: This module executes the transition of control roles in milliseconds. By synchronizing I/O Link timing, it prevents valve chattering or sensor signal drops during the transition, maintaining the safety integrity of sensitive petrochemical or pharmaceutical loops.
Integrated Hardware Diagnostics: A robust front-panel LED array provides immediate visual confirmation of the redundancy state. Technicians can identify synchronization errors or hardware health issues at a glance, significantly reducing Mean Time to Repair (MTTR) in complex DCS environments.
Enhanced Environmental Protection: The module architecture supports conformal coating, providing resilience against G3-rated harsh environments. This shields the 51309283-300 printed wire assembly from corrosive gases and moisture, ensuring long-term reliability in wastewater or refinery applications.
Dual-Slot Physical Stability: Occupying two slots in the Series-A chassis increases the physical stability of the module and allows for superior heat dissipation. This design prevents thermal throttling and maintains performance during the high-load data cycles required for redundant synchronization.

FAQs

What is the difference between part number 51309288-275 and board 51309283-300?

51309288-275 refers to the complete, orderable module assembly (TK-PRR021), whereas 51309283-300 is the specific Printed Wire Assembly (PWA) found inside the housing. They refer to the same functional redundancy hardware.

Does this module support hot-swapping?

Yes. In a redundant configuration, you can replace the failed redundancy module while the system is powered and the other controller is active. However, you must follow the specific Series-A removal and insertion procedures to avoid bus disturbances.

How do I verify if the modules are properly synchronized?

Observe the "Sync" LED on the front panel. A solid LED indicates a successful data link between the two processors. If the LED flashes or remains dark, the module has detected a mismatch or link failure between the redundant pair.

Can I use this module in a C300 Series-C chassis?

No. The TK-PRR021 is designed exclusively for the Series-A chassis used by C200 controllers. C300 systems utilize the Series-C IOTA and a different redundancy cable strategy.
