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.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned for dual-slot installation within the Series-A chassis platform.\u003c\/li\u003e\n\u003cli\u003eSupports seamless, bumpless transfer between primary and backup control units.\u003c\/li\u003e\n\u003cli\u003eConformal coated for enhanced protection in harsh or corrosive industrial atmospheres.\u003c\/li\u003e\n\u003cli\u003eHazardous location certified: Class I, Division 2, Groups A, B, C, D (T4A temperature rating).\u003c\/li\u003e\n\u003cli\u003eIntegrated relay contacts for reliable redundancy status signaling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOil and Gas: Critical process control, pipeline monitoring, and terminal automation.\u003c\/li\u003e\n\u003cli\u003eChemical and Petrochemical: Batch processing, reactor safety, and environmental monitoring.\u003c\/li\u003e\n\u003cli\u003ePower and Utilities: Turbine control, plant-wide distribution, and auxiliary system management.\u003c\/li\u003e\n\u003cli\u003eWater and Wastewater: Automated pump station control and flow management.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eTK-PRR021\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e51309288-375\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlatform\u003c\/td\u003e\n\u003ctd\u003eExperion PKS Series-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Slots\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFailover Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;100 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Transfer Rate\u003c\/td\u003e\n\u003ctd\u003eUp to 1 Gbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e1500V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 degC to +60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 degC to +85 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95% (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Requirements\u003c\/td\u003e\n\u003ctd\u003e1.2V (7mA), 3.3V (0.75A), 5V (1A), 24V (0.09A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePower down the chassis power supply before inserting or removing the module to prevent electrical transients.\u003c\/li\u003e\n\u003cli\u003eAlign the module with the designated chassis slot pair, ensuring the circuit board guides are properly seated.\u003c\/li\u003e\n\u003cli\u003eSlide the module until it interfaces with the backplane connector, then apply firm pressure to the top and bottom of the bezel.\u003c\/li\u003e\n\u003cli\u003eEngage the upper and lower retaining tabs to securely lock the module into the chassis frame.\u003c\/li\u003e\n\u003cli\u003eEnsure the environment meets the specified temperature and humidity ratings to maintain system integrity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the significance of the TK prefix?\u003c\/h3\u003e\u003cp\u003eThe TK prefix denotes that the module includes conformal coating.
