The Schneider Electric Acti9 iTLm is a modular impulse relay. This 1P device has 1 normally open contact. Rated current is 16A, 24VAC to 250VAC operating voltage and it operates with 230VAC to 240VAC or 110VDC control voltage. Electrical endurance goes up to 200000 cycles for AC-21 or 100000 cycles for AC-22. The switching frequency is 5 switching operations/minute or 100 switching operations/day. The impulse relays allow latched type control orders from a changeover contact (switch, time switch, thermostat)
It is mainly used for lighting control applications
The Ui rated insulation voltage is 440VAC
