Multi IO Extension 592

The Multi IO Extension 592 for shutter has been specially developed for the control of blinds and shutters. The double relay is connected to only one output of a KNX Multi IO 570 or KNX IP Multi IO 580. The direction control of the relay outputs is performed automatically by the KNX Multi IO by a defined voltage interruption of the holding current.

The outputs are electro-mechanically locked against each other to prevent a motor defect. The Multi IO Extension 592 has an integrated fuse to protect high-quality equipment.
