System Distribution Box for 16 Segments and 8 Special-Use Areas When using the flexROOM application, the system distribution box can cover up to 24 segments and eight special areas across all three building systems (lighting, shading and air-conditioning). The Modbus RTU or EnOcean, DALI, SMI and MP-Bus sub-bus systems are used for this. Function Lighting: 16 lighting groups (max. 64 ECGs), 12 multi-sensors via DALI Multi-Master (753-647) Sun protection: 16 sun protection drives (SMI) via SMI Master (753-1630) Room climate: 4-pipe system for heating/cooling ceiling (6-way valve), 8 valve actuators (MP-Bus), 8 dew point sensors (via MP-Bus drive) via MP-Bus Master (750-643) Room climate: 16 window contacts via 16-channel digital input (750-1405) General Information Power supply (1-phase), 1st phase: controller, MP-Bus Network (Ethernet) 2 x RJ-45 (Cat.6) Controller PFC200 (750-8212) Interface for operation: RS-485 plug for onboard interface (750-960; RS-485 RBG or EnOcean Gateway, not included) Power supply: for controller: 24 VDC / 2.5 A via switched-mode power supply (787-1712) for valve actuators: 24 VDC / 5 A via switched-mode power supply (787-1722) for DALI bus supply: 18 VDC / 1.1 A via switched-mode power supply (787-1007) Power loss (components): 33.98 W
