blind act. 4-g AC 230 V man.act. KNX DRA

Blind actuator, 4-gang AC 230 V DC 12 - 48 V with manual actuation for KNX DRA plus Blind actuators with integrated bus coupler, manual activation, and status display for each output. For controlling electrically operated blinds, shutters, awnings, ventilation flaps, or similar hangings. Features: Curtain position can be directly controlled. Slat position can be directly controlled. Behaviour after bus voltage failure and recovery can be set. Separately parameterisable movement times with movement time extension for moving into the upper end position. Central control of all blind outputs possible. Feedback of the curtain position or slat position. Feedback can be delayed until after the recovery of bus voltage. Assignments of up to five different safety functions (three wind alarms, one rain alarm, one frost alarm) or optionally with cyclical monitoring. Forced setting function can be realised for each blind output. Integration in scenes is possible, 8 internal scenes at the most can be parameterised per channel. Memory function for light scenes. Sun protection function with fixed and variable curtain or slat positions can be activated. Extended sun protection with extensive control functions. Integration in temperature management of building possible. Blocking of individual outputs manually or with bus. Active or passive (object can be read out) cyclical feedback functions. Building site operation: Outputs can be operated manually without bus voltage with operating voltage only. For mains voltage AC 230 V (4 channel) or low voltage DC 12 to 48 V (2 channel). Connection of various external conductors. Independent control of the four blind outputs. Automatic curtain moving time detection for AC 230 V drives with mechanical stop position switches. Notes : Installation on DIN top-hat rail. VDE approval in accordance with EN 60669-1, EN 60669-2-1.
