Extron DBF ETR COCA Dual-Button Feedback eBUS Expansion Module with...
The Extron DBF ETR COCA is a compact, eBUS-enabled expansion module designed to add dual-button feedback, contact closure inputs, and relay outputs to Extron control systems. It provides reliable interfacing for external buttons, switches, sensors, or dry-contact devices while delivering visual feedback through integrated LEDs and supporting relay control for devices like screens, lights, or shades.
This module excels at extending control capabilities in environments where additional physical inputs or relay-driven outputs are needed without requiring full-size controllers or complex wiring. The dual-button design with LED feedback allows users to see system status at a glance (e.g., power on/off, mode active), while the contact closure inputs detect external triggers and the relay outputs control low-voltage loads with simple on/off or momentary actions.
Constructed with durable plastic housing and a small footprint, the DBF ETR COCA mounts discreetly behind panels, inside lecterns, or within furniture. The eBUS daisy-chain architecture enables easy expansion of existing control systems using a single eBUS cable for power and communication, reducing installation complexity and cabling requirements.
Primary applications include conference room tables, instructor stations, lecterns, podiums, and control closets where additional button feedback, sensor inputs, or relay control is required. It is particularly valuable in classrooms, boardrooms, training facilities, and auditoriums needing to interface with external switches (e.g., wall plates, foot pedals) or control low-voltage devices (e.g., projector screens, room dividers, lighting relays) as part of an integrated AV control system.
Compatibility centers on Extron eBUS-enabled products, including MediaLink Plus Controllers (MLC Plus series), IPCP Pro Series control processors, and other eBUS expansion modules. The module integrates seamlessly into eBUS networks, supporting daisy-chained connections with eBUS power and communication over a single pair of wires. It pairs well with Extron TouchLink Pro touchpanels, Global Configurator programming, and GlobalViewer Enterprise for centralized system management.
Installation is straightforward and low-impact: mount the module behind a panel or inside furniture using the included hardware, connect the eBUS cable to the network (daisy-chain capable), wire contact closure inputs from external switches/sensors, connect relay outputs to controlled devices (dry-contact rated), and configure button functions, LED feedback, and relay behavior via Extron Global Configurator software. The compact design and eBUS topology minimize wiring runs and support future expansions without rewiring.
