Description Reviews

The Honeywell TK-PRR021 (51309288-375) is a critical redundancy module designed for the Experion PKS Series-A control architecture. This module facilitates high-availability operations by managing synchronization and failover between redundant C200 or C200E control processors. By maintaining a constant state of readiness, the TK-PRR021 ensures that the standby controller can assume control functions in less than 100 ms, preventing process disruption during primary controller faults.

Features

Designed for dual-slot installation within the Series-A chassis platform.
Supports seamless, bumpless transfer between primary and backup control units.
Conformal coated for enhanced protection in harsh or corrosive industrial atmospheres.
Hazardous location certified: Class I, Division 2, Groups A, B, C, D (T4A temperature rating).
Integrated relay contacts for reliable redundancy status signaling.

Applications

Oil and Gas: Critical process control, pipeline monitoring, and terminal automation.
Chemical and Petrochemical: Batch processing, reactor safety, and environmental monitoring.
Power and Utilities: Turbine control, plant-wide distribution, and auxiliary system management.
Water and Wastewater: Automated pump station control and flow management.

Installation Guidelines

Power down the chassis power supply before inserting or removing the module to prevent electrical transients.
Align the module with the designated chassis slot pair, ensuring the circuit board guides are properly seated.
Slide the module until it interfaces with the backplane connector, then apply firm pressure to the top and bottom of the bezel.
Engage the upper and lower retaining tabs to securely lock the module into the chassis frame.
Ensure the environment meets the specified temperature and humidity ratings to maintain system integrity.

FAQ

What is the significance of the TK prefix?

The TK prefix denotes that the module includes conformal coating. This makes the hardware suitable for installation in corrosive or harsh industrial environments where standard components might degrade.

Does this module require specific wiring connectors?

Yes, this module is designed to interface with the 36-pin TC-TBCH field wiring connector.

Can this module be used with non-C200 controllers?

The TK-PRR021 is specifically engineered for the Honeywell C200 and C200E control processor redundancy architecture within the Experion PKS system.
