This module uses high-speed fiber optic communication to synchronize data between the primary and secondary chassis, ensuring uninterrupted control in the event of a failure. The RM2 version supports redundancy over distances up to 10 kilometers using SFP transceivers.\u003c\/p\u003e\r\n\u003ch2\u003eKey Features\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eSupports controller redundancy for ControlLogix systems\u003c\/li\u003e\r\n\u003cli\u003eFiber optic communication between primary and secondary chassis\u003c\/li\u003e\r\n\u003cli\u003eUses Small Form-factor Pluggable (SFP) modules for flexible fiber options\u003c\/li\u003e\r\n\u003cli\u003eEnables bumpless switchover during primary controller failure\u003c\/li\u003e\r\n\u003cli\u003eCompatible with Logix 5000 controllers and Studio 5000 software\u003c\/li\u003e\r\n\u003cli\u003eSupports redundancy over long distances (up to 10 km)\u003c\/li\u003e\r\n\u003cli\u003eEnhanced synchronization and status diagnostics\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eCommunication Type\u003c\/strong\u003e: Fiber optic via SFP transceivers\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eRedundancy Support\u003c\/strong\u003e: Primary–Secondary controller synchronization\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSynchronization Rate\u003c\/strong\u003e: ≤20 ms (typical)\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eDistance Support\u003c\/strong\u003e: Up to 10 km (with appropriate SFP modules and fiber cables)\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 1 ControlLogix chassis slot\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: ControlLogix chassis (any standard slot)\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption\u003c\/strong\u003e: Approx. 5.6W\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e: 0°C to 60°C\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eCompatible Software\u003c\/strong\u003e: Studio 5000 Logix Designer v20 and later\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cstrong\u003eRequired Modules\u003c\/strong\u003e: One per chassis in a redundant pair\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eApplication Areas\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eProcess automation with high- availability requirements\u003c\/li\u003e\r\n\u003cli\u003eOil and gas pipeline monitoring\u003c\/li\u003e\r\n\u003cli\u003ePharmaceutical production\u003c\/li\u003e\r\n\u003cli\u003ePower generation and distribution control\u003c\/li\u003e\r\n\u003cli\u003eWater and wastewater treatment facilities\u003c\/li\u003e\r\n\u003cli\u003eAny system requiring controller failover and minimized downtime\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eAdvantages\u003c\/h2\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eProvides seamless redundancy for critical systems\u003c\/li\u003e\r\n\u003cli\u003eReduces risk of process interruption and production loss\u003c\/li\u003e\r\n\u003cli\u003eFlexible fiber distance allows remote redundancy architectures\u003c\/li\u003e\r\n\u003cli\u003eDiagnostic LEDs and software tools simplify setup and monitoring\u003c\/li\u003e\r\n\u003cli\u003eProven solution for industrial high-availability automation needs\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Rabwellplc","offers":[{"title":"Default Title","offer_id":47603326615788,"sku":"30\/1756-RM2","price":1807.85,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0825\/7044\/5036\/files\/10_6255ec84-fccb-4f5a-bd98-9ca1b00daebd.jpg?v=1778059919","url":"https:\/\/rockwellplc.com\/products\/plc-allen-bradley-1756-rm2-ser-a-controllogix-redundancy-enhanced-module-ab-1756rm2","provider":"rockwellplc","version":"1.0","type":"link"}
