PRODUCT DESCRIPTION
The Economic staircase timer is a modular device designed for controlling electrical circuits in lighting
installations. The device is used in both domestic and industrial spaces, where it can control lighting,
ventilation, heating or signalling.
The relay is supplied with 230V AC/DC at a frequency of 50/60Hz. It has one NO contact with a rated
switching current of 16A for 250V AC and 24V DC. The maximum power is 4000VA.

The device has as many as 6 operating modes:
- ON for a set interval triggered by applying the supply voltage or closing of the control contact S (AUTO),
- OFF delay with the control contact S (R),
- ON for the set interval controlled by closing of the control contact S, with the function of switching off the
output relay R prior to the lapse of the interval T (Wi),
- Permanent switching on (ON) / off (OFF).
- AUTO, R and Wi may work with an additional EXTRA TIME mode, where after the time in the basic mode has
elapsed, the R contact is switched off for 1 s and then switched on again for 10 s. After the 10 s time has
elapsed, the R contact is disconnected.
It is designed to be mounted on a 35 mm DIN rail in any position with the help of two catches - top and
bottom. The unit has terminals for wires up to 2.5 mm².
The compact dimensions of 65x18x90 mm and the width of one module ensure that the installation is
convenient and space in the switchboard is saved.
The product complies with EN/IEC 60529 standards.
