System Distribution Box for 24 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: 32 lighting groups (max. 64 ECGs), 24 multi-sensors via 2 x DALI Multi-Master Module (753-647) Sun Protection: 32 sun protection drives (SMI) via 2 x SMI Master (753-1630) Room climate: Heating/cooling ceiling, 4-pipe system (6-way valve), 24 valve actuators (MP-Bus), 24 dew point sensors (via MP-Bus drive) via 3 x 750-643 MP-Bus master Room climate: 24 window contacts via 2 x 16-channel digital input (750-1405/ 1 x channel 1 … 16, 1 x channel 1 … 8) Special-Use Areas Lighting: 8 ECGs or 8 lighting groups (max. 64 ECGs), 16 multi-sensors via DALI Multi-Master Module (753-647) Sun protection: 16 sun protection drives (SMI) via SMI Master (753-1630) Room climate: Heating/cooling 4-pipe system (6-way valve), 8 valve actuators, 8 dew point sensors via MP-Bus master (750-643) Room climate: 8 window contacts via 16-channel digital input (750-1405/channel 9 … 16) General Information Power supply (3-phase), 1st phase: controller, 2nd phase: DALI, 3rd phase: 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 / 10 A via switched-mode power supply (787-1732) for DALI bus supply: 18 VDC / 1.1 A via switched-mode power supply (787-1007) Power loss (components): 37.88 W
