The ELKO SJR-2/UNI is a time delay relay with 2C DPDT output and rated 16 A, driven by a 12-240 VAC/DC input.
It is adjustable from 0.1 s to 10 days and set by a rotary switch and potentiometer.
Its second delay adjusts from 0.1 s to 10 days (t2, set independently).
Build option: two independently set delays for staged switching of high loads.
It has DIN Rail mounting.
