System Distribution Box for 8 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: 8 sun protection drives (conventional) via 16-channel digital output (750-1504) Room climate: Heating/cooling ceiling, 4-pipe system (6-way valve), 4 valve actuators (digital outputs) via 4-channel digital output (750-504) Room climate: 4 dew point sensors (digital inputs), 4 window contacts via 8-channel digital input (750-430) General Information Power supply (3-phase), 1st phase: controller, 2nd phase: sunblind 1-8, 3rd phase: reserve 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/field devices: 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): 24.4 W
