Functional Devices RIBMNLB-6 Logic Board
The Functional Devices RIBMNLB-6 is a 6-input logic board designed for high-reliability AHU fan safety alarm circuits and general-purpose logic applications. This track-mount device streamlines complex relay logic by integrating six normally closed (N/C) inputs that control a single master relay. When any of the monitored inputs open—whether from a low temperature alarm, smoke detector, or high pressure switch—the master relay trips, providing an essential shutdown signal for HVAC air handling units. The board operates on 24 Vac/dc power and is specifically engineered as a half wave device; technicians must ensure it is not powered on the same transformer as full-wave devices to prevent equipment damage.
Built for the professional contractor, the RIBMNLB-6 includes a MT212-6 mounting track and features individual LED status indicators for all inputs and the master relay. It offers three distinct outputs: two 24V terminals and one dry-contact output rated up to 10 Amps at 277 Vac. For systems with fewer than six monitored points, the logic board includes integrated bypass switches for unused inputs, ensuring the master alarm circuit remains functional without unnecessary wiring. This UL listed logic circuit simplifies DDC controller integration by providing clear contact closure outputs to pinpoint the exact cause of a system shutdown.
Key Benefits- Simplified Fan Safety Logic: Consolidates up to six safety inputs into one master relay output, reducing wiring complexity in AHU control panels.
- Visual Troubleshooting: Local LED indicators for each input allowing technicians to quickly identify which safety circuit triggered a shutdown.
- Flexible Integration: features selective bypass switches for each input, enabling full functionality even when using fewer than six safety devices.
- High Compatibility: Rated for 24 Vac/dc power with 10 Amp dry contacts suitable for a wide range of industrial and commercial HVAC control systems.
Can I use this board with normally open (N/O) sensors?
The standard RIBMNLB-6 is designed specifically for normally closed (N/C) safety strings. If your project requires normally open logic, you should specify the RIBMNLB-6NO model.
How do I handle unused inputs on the logic board?
This device features on-board bypass dip switches. Simply close the switch for any terminal pair not in use to maintain the continuity of the master relay circuit.
What are the power requirements for the master relay?
The board operates on 24 Vac/dc. However, as a half wave device, it is critical to use a dedicated transformer or verify the rectification type of other connected 24V components to avoid shorts.
