System Distribution Box for 16 Segments 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 / 0.2 A via DC/DC Converter (753-620) Power loss (components): 32.2 W
