ELSNER 70535 KNX S4-B12 DES Actuator for 4 Drives with 3 Limit

The ELSNER 70535 product is a specialized device for the control and management of building automation systems, particularly suitable for KNX applications.

Key Features

• 24 V DC internal power supply for inputs and outputs.
• 4 outputs with polarity change for 12-24 V DC motors, ideal for shading and window management.
• Keyboard with 4 pairs of buttons and status LEDs.
• 12 binary inputs that can be used as manual switches or as bus switches with variable voltage (6-24 V DC).

Measurement and Feedback

• Automatic measurement of engine operating time, including notification of any faults.
• Feedback on the position of movement, including the position of the slats for the curtains.
• Storage of the motion position by means of a 1-bit object (storage and recall, for example, by means of buttons).

Control and Scenarios

• Internal or external control through automation.
• Integrated shading control for each engine output, with tracking the position of the sun for the curtains.
• Scene control for the movement position with 16 scenarios for each motor (including the position of the blades for the curtains).
