    FAQs

    Q1: What is the primary function of the TC-PRR021?

    It is a Control Processor Redundancy Module that enables fully fault-tolerant dual-chassis control configurations in C200/C200E and Experion LS systems. It works alongside C200/C200E control processors to provide seamless controller redundancy, ensuring continuous process execution during processor failures .

    Q2: Is the TC-PRR021 still in production?

    No. The C200/C200E series was phased out by Honeywell on December 31, 2020. The module is available only through aftermarket suppliers as legacy/spare-part stock. Honeywell recommends migration to the C300 Controller or ControlEdge UOC for new installations.

    Q3: What is the switchover time for this redundancy module?

    The TC-PRR021 provides automatic failover with a switchover time of less than 50 ms, ensuring minimal process disruption during primary processor failure.

    Q4: Does the TC-PRR021 support hot-swap?

    Yes. The module supports Removal and Insertion Under Power (RIUP) in ordinary, non-hazardous locations. RIUP is NOT permitted in Class I, Division 2 hazardous locations without a hot work permit.

    Q5: What is the difference between TC-PRR021 and TK-PRR021?

    The TC-PRR021 is the standard non-coated version. The TK-PRR021 is the conformally coated version for enhanced protection in harsh industrial environments. Both provide identical redundancy functionality.
