The drive can be controlled by any 0 ÷ 10 V analogue output of the Foxtrot system. It is recommended to use the C-IR-0202S module for control at the drive location; the module is fitted with a 0 ÷ 10 V analogue output, and also with two inputs (e.g. the temperature in the room and the window contact). When multiple drives are powered from a common 24 VAC supply, it is necessary to take care of the galvanic connection of analogue outputs of individual CIB modules with the CIB communication and 24 V powering of the drives. The negative terminal of the power supply and the negative CIB terminal are interconnected via the analogue output circuits - it is important to keep the minimum voltage difference between both signals (the same topology of cables, sufficient CIB cables cross-section and 24 VAC power supply for the drives).

Notes:
-
When multiple AA 5004 drives are controlled, constant consumption of about 1.8 W per drive must be considered (the switching current up to 200 mA for maximum two minutes per each drive).
-
The input resistance of the AA 5004 drive analogue input is 100k.
-
If multiple drives are to be powered from a common 24 VAC source, you must take into account the galvanic connection of the source and the CIB (via the drive analogue input) - the CIB bus and the 24 VAC supply must always be lead in stronger wires and along the same route.
-
With greater cable lengths (dozens of meters), it is recommended to use the motor CIB drives or on-off actuators.
