System Distribution Box for 16 Segments and 4 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 (conventional) via 2 x 16-channel digital output (750-1504/Channel 1 … 8) Room climate: Heating/cooling ceiling, 4-pipe system (6-way valve), 8 valve actuators (digital outputs) via 16-channel digital output (750-1504/channel 1 … 8) Room climate: 8 dew point sensors (digital inputs), 8 window contacts via 16-channel digital input (750-1405) Special-Use Areas Lighting: 4 lighting groups (max. 16 A/group) via 8-channel digital output (750-530/channel 1 … 4) Sun protection: 4 sun protection drives (conventional) via 16-channel digital output (750-1504/channels 9 … 16) Room climate: Heating/cooling ceiling, 4-pipe system (6-way valve), 4 valve actuators (digital outputs) via 8-channel digital output (750-530/channel 5 … 8) Room climate: 4 dew point sensors (digital inputs), 4 window contacts via 8-channel digital input (750-430) General Information Power supply (1-phase), 1st phase: controller Power supply (1-phase), 1st phase: conventional lighting Power supply (3-phase), 1st phase: sunblind 1-8, 2nd phase: sunblind 9-16, 3rd phase: sunblind 1-4 SNB 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): 43 W
