Eltako SU12DBT/1+1-UC

2-channel timer switch with display and Bluetooth. Channel 1 features a potential-free relay with 16A/250VAC and DX. Channel 2 has a potential-free OptoMOS semiconductor output with 50mA/12V. This timer switch is suitable for controlling an electronic relay or a pulse group switch, for example. It offers display lighting and an astro function. The standby loss is only 0.1-0.3 watts. The supply voltage and control voltage for the central control unit is 12-230V.

The device is a rail-mounted unit for installation on a mounting rail according to DIN-EN 60715 TH35. It has a width of 18 mm and a depth of 58 mm. With the patented Eltako duplex technology, the normally potential-free contact 1 can switch 230V/50Hz alternating current at zero crossing, which drastically reduces wear. For this purpose, the neutral conductor is connected to the terminal (N) and L to 1 (L), resulting in an additional standby loss of only 0.1 watts.

Up to 60 timer memory slots can be distributed across the channels, with date and automatic switching for summer and winter time. The power reserve without a battery is approximately 7 days. Each memory slot can be assigned either with the astro function (automatic switching at sunrise or sunset), the on and off times, or a pulse switching time (default state 2 seconds). The on or off time of the astro function can be shifted by up to ± 2 hours. Additionally, a time shift influenced by the solstices of up to ± 2 hours can be entered.

The timer switch has a control input (+A1) for central control ON or OFF with priority. The settings can be made either via Bluetooth with the app or using the MODE and SET buttons, with a key lock option available. Pressing MODE or SET activates the display lighting. 20 seconds after the last operation of MODE or SET, the program automatically returns to normal display mode and the display lighting is turned off.
