Installed in a redundant chassis pair, it provides the hardware interface required for coordination between redundant controllers. The module uses a dedicated redundancy cable to connect the corresponding modules in the two chassis.\u003c\/p\u003e\n\u003ch3\u003eFunction and System Role\u003c\/h3\u003e\n\u003cp\u003eThe TC-PRR021 is part of the Honeywell Experion chassis-based control architecture. It supports a redundant controller configuration in which two C200\/C200E controller chassis operate as a primary and backup pair.\u003c\/p\u003e\n\u003cp\u003eThe redundancy modules establish the connection between the two chassis through a dedicated redundancy cable. This arrangement supports controller redundancy rather than redundant field I\/O or power regulation.\u003c\/p\u003e\n\u003ch3\u003eRedundancy Cable and Status Monitoring\u003c\/h3\u003e\n\u003cp\u003eEach redundant chassis requires its own TC-PRR021 module. The two modules are connected using a dedicated fiber-optic redundancy cable. Honeywell documentation identifies the following cable options:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGN-KRR011: 1 m redundancy cable.\u003c\/li\u003e\n\u003cli\u003eGN-KRR031: 3 m redundancy cable.\u003c\/li\u003e\n\u003cli\u003eGN-KRR101: 10 m redundancy cable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe module also provides a Status Contact Interface on applicable hardware versions. Its optically isolated solid-state relay contact remains closed when the module operates as the primary and opens when it changes to secondary\/backup status or loses power. This contact can be connected to an external monitoring circuit.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eTC-PRR021\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e51309288-225\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRedundancy Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem\u003c\/td\u003e\n\u003ctd\u003eHoneywell Experion C200 \/ C200E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Function\u003c\/td\u003e\n\u003ctd\u003eController redundancy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Occupancy\u003c\/td\u003e\n\u003ctd\u003e2 slots (double-wide)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eChassis-mounted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Connection\u003c\/td\u003e\n\u003ctd\u003eDedicated fiber-optic cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Monitoring\u003c\/td\u003e\n\u003ctd\u003eOptically isolated solid-state relay contact on applicable versions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation and Configuration\u003c\/h3\u003e\n\u003cp\u003eThe TC-PRR021 is installed as a pair, with one module in each chassis of the Redundant Chassis Pair (RCP). Honeywell specifies the following default slot positions, using zero-based numbering:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10-slot and 17-slot chassis: slots 5 and 6.\u003c\/li\u003e\n\u003cli\u003eOther chassis models: slots 4 and 5.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBoth chassis must contain the corresponding C200\/C200E control processors.

A redundant controller configuration requires two TC-PRR021 modules, one in each chassis, connected by a compatible redundancy cable.\u003c\/p\u003e\n\u003cp\u003eQ: Can the TC-PRR021 be installed in any chassis slot?\u003c\/p\u003e\n\u003cp\u003eA: No. Honeywell specifies default slot positions according to chassis size. The 10-slot and 17-slot chassis use slots 5 and 6, while other chassis models use slots 4 and 5. Confirm the complete chassis configuration before installation.\u003c\/p\u003e\n\u003cp\u003eQ: Does the TC-PRR021 provide an external controller status signal?\u003c\/p\u003e\n\u003cp\u003eA: Applicable versions provide an optically isolated solid-state relay contact through the Status Contact Interface. The contact indicates primary, secondary\/backup, or loss-of-power status through its open\/closed state. Some earlier hardware versions do not include this connector.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52750278328605,"sku":"TC-PRR021","price":9.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/5387\/3181\/files\/1-12_1000.jpg?v=1787024211","url":"https:\/\/www.6gcontrols.com\/pt\/products\/honeywell-tc-prr021-redundancy-module","provider":"6G Controls","version":"1.0","type":"link"}
