This redundancy module is the hardware foundation for mission-critical process control, enabling synchronized state-mirroring between primary and secondary controller racks. By occupying two physical chassis slots, the unit provides the high-speed data link required to ensure a seamless, bumpless transfer of control logic and I\/O status in the event of a processor or power failure in the active rack.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModel Identification\u003c\/strong\u003e:\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTC-PRR021\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAssociated Part Number\u003c\/strong\u003e:\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e51309288-225\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePrimary Function\u003c\/strong\u003e: Controller Redundancy and State Synchronization\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePlatform Compatibility\u003c\/strong\u003e: Honeywell Experion PKS C200 Systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 24 VDC (Internal Backplane Power)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCurrent Consumption\u003c\/strong\u003e: 90 mA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Large-format module occupying 2 Chassis Slots\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCommunication Interface\u003c\/strong\u003e: Dedicated redundancy link ports for inter-chassis connection\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Weight\u003c\/strong\u003e: 0.41 kg (approx. 0.90 lbs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLifecycle Status\u003c\/strong\u003e: Discontinued by Manufacturer (Legacy Support available)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSystem Redundancy and Uptime\u003c\/h2\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTC-PRR021 (51309288-225)\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eoperates by maintaining a constant, high-speed heartbeat and data exchange between two C200 controller pairs. This \"Redundancy Cable\" link ensures that the standby controller is always updated with the latest process variables and PID loop states. In industrial facilities where process interruption is not an option, this module eliminates single points of failure at the controller level. Its relatively low power draw (90 mA) allows for high thermal stability within the control cabinet, even during intensive data synchronization tasks.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this module require a specific redundancy cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTC-PRR021\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003emust be connected to its counterpart in the redundant chassis using a dedicated, high-speed redundancy cable (often part of the TC-KRC series) to function correctly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this module in a single-chassis configuration?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile the hardware will fit, the module's purpose is to manage a pair of chassis.
