This Acti9 iRTA is an operating Time delay relay. The time delay range is 0.1s to 100h. It delays emergizing of a load. The single time daily cycle starts at the switching ON of the iRTA relay power supply. The Uc control and power supply voltage is from 24VAC to 240VAC +/- 10% and 24VDC +/- 10%. The load is energized at the end of the time delay T. The operating frequency is 50Hz or 60Hz. The precision of the device is +/- 10% of the full scale. The minimum duration of control impulse is 100ms. The maximum resetting time per voltage interruption is 100ms. The nominal switching current is 21A at 250VAC. The mechanical endurance under AC1 category is over 5 x 10exp6 switchning operations. The electrical endurance under AC1 category is over 10exp5 switchning operations. The type of excitation is analog (ou analogue) with single function. The device is flashing during time delay. It includes a changeover contact. The width in 9mm pitches is 2. The degree of protection is IP20. The dimensions are (W) 18mm x (H) 90mm x (D) 72mm. The weight is 65g. The operating temperature is -5°C to + 55°C. The storage temperature is -40°C to + 70°C.
