Description Time Switch
The MDT Time switch with 20 channels (8 cycle times for each channel) has a daily/weekly/Astro switching function and an adequate power reserve if the bus voltage fails. The cycle times of the single channels are adjustable by the ETS or can be set directly at the device.
The large active color display for comfortable handling allows direct switching of the 20 channels (Manual Mode).
The time switch offers cyclic sending of the time on the KNX bus and clock time adjustment by bus telegram (Master-/slave mode).
The 8 logical blocks with 4 inputs each allow individual conjunctions.
The MDT Time Switch is a modular installation device for fixed installation in dry rooms. It fits on DIN 35mm rails in power distribution boards or closed compact boxes.
