The I-520 is a 24-hour weekly timer with a 2x16 mm LCD display that connects to 230VAC. The I-521 is identical to the I-520 as a weekly timer, but it only connects to 12VDC. The transformer encapsulated in its PCB has been removed.
It supports up to 50 weekly programs and allows you to program the output from a minimum of 1 second to a maximum of 59 minutes and 59 seconds (almost 1 hour), from Monday to Sunday.
It incorporates an internal E2PROM memory, which allows you to retain the data even in the event of a power outage or occasional power failures.
Like all new Cebek products, this new weekly programmer has been designed with DIN rail dimensions, which will facilitate its incorporation into electrical panels, using the Cebek DIN rail support ref C-7588.
The output is relay-based, and supports a maximum load of 7 A, and 2 A for inductive loads.
To facilitate the installer's programming, it also offers 4 pre-programmed and very common programming modes, which we will describe below:
1/ That it is activated on a specific day of the week at a specific time.
2/ That it is activated every day of the week, at the same time, and every day.
3/ That it be activated, from Monday to Friday, at the same time (but not on Saturday or Sunday)
4/ That it is activated, on Saturday and Sunday, at the same time (remaining deactivated during the week).
Regarding the display, the text on the screen is currently configurable in 2 languages: Spanish and English.
