DIN rail staircase timer with adjustable time delay, ideal for corridor lighting and energy-saving control.The Aist 8 is a DIN rail-mounted staircase timer switch, designed for automatic control of corridor lights, stairwell lamps, and ventilation systems. With an adjustable time delay setting, it automatically turns off lights after a preset period to save energy.
Description:
– Staircase time switch, electro-mechcanical
– 4 conductor with floor lighting connection
– 3 conductor without floor lighting (no longer permitted for new systems)
– Retriggerable
– No closed-circuit current consumption
– Toggle switch for permanent light ON
– Reliable due to synchronous motor drive
– Simplest possible time setting and direct delay time readout on absolutescale
– Precision mechanics and therefore exact switching period
– Very low sensitivity to interference
