Suevia DIN rail mount timer digital Data Log II 230 Vac 16 A/250 V Data Log II Data Sheet

The DATA LOG 2  is a digital time switch with 2 independent  change-
over and potential free circuits  designed to control of any electrical ins-
tallation. Its possibilities include short-duration (1-59 seconds) swit-
ching, repeating cycles, random programming, automatic summer-win-
ter time change and a time counter.

Its menus can be displayed in 5 languages and it displays a chrono-
gram that shows in the display the programming of current day, both cir-
cuit C1 and C2. To change chronogram from C1 to C2, just press key
“ C “ (C1 – C2 ). This divided into 48 section, each section representing
30 minutes. The section corresponding to the current time flashes.

ATTENTION: Electrical devices must be installed and assembled by
authorized installer. 

VERY IMPORTANT: The switch is protected internally against interfe-
rence by a safety device. However, particularly strong electromagnetic
fields may alter is operation. Such interference can be avoided by
adhering to the following recommendations during installation:

- The device should not be installed near inductive loads (motors, 
transformers, contactors, etc..)

- A separate power line is recommended ( equipped with a network
filter if necessary).

- Inductive loads should be equipped with interference suppressors
(varistor, RC filter).

If the timer switch is to be used in combination with other devices in an
installation, it is necessary to verify that no parasitic disturbances will be
caused by the group

ASSEMBLY: They should be installed in switchboard cabinets made of
35mm symmetric sections  in accordance with EN 50 022.
