Bena M is a medium-sized integrated system featuring 29 relay controls (8+5+16). The 8 channels can be configured as 4 pairs for hardware-interlocked curtain/sheer controls, preventing simultaneous motor activation in both directions, essential for motor units sensitive to such conditions.
It includes two 0-10V analog outputs, supporting dimming circuits, variable valve control, and fan speed adjustments. Additionally, Bena M enables direct control of three-speed fan coil units and four-pipe HVAC systems.
With up to 24 inputs and 12 outputs, the system seamlessly connects to multiple sensors and indicators. Bena M is network-ready and can be integrated into Benalla’s Guest Room Management System, enhancing operational awareness and efficiency. For added functionality, up to 8 B2KPro modules can be incorporated.
Sample use case:
- Standard to medium-sized rooms/suites (20-50 sqm)
- Public spaces like corridors and lift lobbies with primarily on/off lighting needs
Key Features
✅ Networked for seamless integration
✅ Scalable to meet evolving requirements
✅ Integrated dimming for enhanced lighting control
