Allen Bradley AB Allen Bradley 1756-SRM ControlLogix Redundancy Module
Overview
Overview The 1756-SRM System Redundancy Module for ControlLogix enables controller-level redundancy by synchronizing two chassis (primary and secondary) over high-speed fiber optics. Upon a primary controller failure, the secondary seamlessly takes over to ensure uninterrupted operation of critical industrial processes. Product Specifications Module Type: ControlLogix System Redundancy Communication Interface: Fiber-optic port with SC connector Supports 62.5/125 µm multimode fiber Slot Requirement: Occupies 2 slots in each chassis Status Indicators: PRI (Primary) COM (Communication) Health LED Backplane Current Draw: 1.2 A @ 5 VDC 0.02 A @ 24 VDC Power Dissipation: 11.3 W Thermal Dissipation: 38.5 BTU/hr Operating Temperature: 0 to 60 °C Storage Temperature: –40 to 85 °C Humidity: 5–95% non-condensing Enclosure Type: Open-style Certifications: UL, CE, Class I Div 2 Installation Notes Requires two identical ControlLogix chassis with matching module layout and firmware Install one 1756-SRM module in each chassis Connect modules using multimode fiber-optic cable with SC connectors Ensure proper grounding and shielding for EMC compliance Use Studio 5000 or RSLogix 5000 for redundancy configuration Perform system qualification after installation to validate synchronization
