Description
The Honeywell TK-PRR021 (51309288-375) is a high-availability Redundancy Module (RM) designed for the Honeywell Experion PKS Series-A control system. This module facilitates the redundant configuration of C200 and C200E control processors, ensuring continuous process operation by managing synchronization and automatic switchover between primary and standby controllers. The "TK" designation indicates that this unit is conformal coated, providing enhanced protection against corrosive industrial environments.
Features
- Supports redundant architecture for C200/C200E control processors
- Occupies two slots in a Series-A chassis
- Conformal coated for harsh environment durability
- Supports bumpless transfer for zero-downtime failover
- Class I, Division 2, Groups A, B, C, D hazardous location certification
- T4A temperature code rating
Applications
- Chemical and petrochemical batch processing and reactor safety
- Oil and gas upstream telemetry and terminal monitoring
- Power and utility turbine control and plant-wide monitoring
- Water and wastewater pump and flowmeter data acquisition
- Pulp and paper automated boiler and roller control systems

Installation Guidelines
- Power Down: Always switch off the chassis power supply before inserting or removing modules to prevent electrical transients.
- Alignment: Ensure the module is held straight, aligning the circuit board guides with the targeted Series-A chassis slot pair.
- Seating: Slide the module smoothly until it engages the backplane connector. Firmly press the top and bottom of the bezel to ensure full contact.
- Securing: Snap the upper and lower retaining tabs inward to lock the module into the chassis frame.
- Handling: Use standard ESD protection practices when handling electronic modules to prevent damage to sensitive components.
FAQ
What is the difference between TK and TC models?
The "TK" prefix indicates that the module is conformal coated, designed specifically for use in harsh or corrosive industrial environments, whereas "TC" models may lack this specific protective coating.
What is the primary function of the TK-PRR021?
It coordinates the dual operation of primary and backup controllers, ensuring that the standby unit can seamlessly take over control functions without process disruption in the event of a primary controller failure.
What type of wiring connection does it use?
The module utilizes a 36-pin TC-TBCH field wiring connector for integration with the Series-A chassis infrastructure.
