Product Description

The TK-CRR014 is a high-availability controller redundancy interface module designed for the Honeywell Experion PKS C300 platform. It provides seamless synchronization between primary and backup controllers, enabling “bumpless” switchover in the event of a hardware failure. This capability is critical for mission-critical industrial processes in oil & gas, power generation, and chemical processing environments.

Housed in a ruggedized IP67 enclosure, the TK-CRR014 offers superior protection against dust and water ingress, while its industrial-grade electronics operate reliably across –40°C to +70°C. Utilizing a proprietary high-speed protocol, the module ensures real-time state mirroring, forming the backbone of fault-tolerant DCS architectures.

Core Applications

  • Fault-Tolerant Control
    Enables C300 controller redundancy for critical loops that cannot tolerate downtime.

  • Remote Enclosure Deployment
    IP67 rating allows installation in harsh field environments outside traditional control rooms.

  • Safety Instrumented Systems (SIS)
    Provides the redundant communication backbone for safety-critical logic solvers.

Frequently Asked Questions

Q: Does the TK-CRR014 handle I/O communication?
A: No. It is dedicated solely to controller synchronization. I/O communication is managed via I/O Link, ControlNet, or Ethernet modules.

Q: What is required for a complete redundant setup?
A: A typical setup requires two C300 controllers, two TK-CRR014 modules (one per controller), and the specialized redundancy cable to link them.
