It operates alongside the CLCN-A paddle board, which handles the “A” cable connection, to ensure full redundancy for uninterrupted control communication. The board supports coaxial and fiber optic connections between TPN modules, with BNC tee connectors for quick connection or safe disconnection. Built to handle demanding industrial environments, it provides electrical isolation up to 1500 VDC and operates over a wide voltage and temperature range, ensuring system reliability even under harsh conditions. Key Features: LCN ‘B’ cable interface: Dedicated to connecting the LCN “B” path in a dual-node chassis for redundant control network operation. Redundant communication support: Works in tandem with the CLCN-A paddle board to maintain continuous operation even if one path fails. BNC tee connectors: Provide secure attachment to LCN “B” and allow a node to be disconnected without affecting the rest of the network. High electrical isolation: Rated at 1500 VDC to safeguard against interference and electrical faults. Wide voltage input range: Operates from 12–24 VDC input with an output voltage range of 5–60 VDC. Multiple channel output capacity: Supports 2 A per channel with a total maximum output of 8 A for system flexibility. Rugged environmental capability: Operates in temperatures from -40°C to 70°C for use in demanding conditions. Compact, lightweight build: Measures 114 × 12.7 × 118 mm and weighs just 0.35 lbs for easy installation. The 51305072-300 delivers the reliability and electrical performance required for mission-critical control networks in industrial environments.
