Timed Relay IRT IRTA

This iRTA Acti9 is an operating time delay relay. The delay range is from 0.1 to 100 hours. It delays the rise of a load. The single daily cycle begins with the power supply connection of the iRTA relay. The control Uc and the power supply voltage range from 24 V AC to 240 V AC +/- 10% and 24 V DC +/- 10%. The load is energised at the end of the time delay T. The operating frequency is 50Hz or 60Hz. The device's accuracy is +/- 10% of the full scale. The minimum control pulse duration is 100ms. The maximum reset time due to voltage interruption is 100 ms. The rated switching current is 21 A at 250 V AC. The mechanical endurance in category AC1 is over 5 x 10exp6 switching operations. The electrical endurance in category AC1 is over 10exp5 switching operations. The excitation type is analogue (our analogue) with a single function. The device flashes during the delay. It includes a changeover contact. The width in 9 mm steps is 2. The degree of protection is IP20. The dimensions are (W) 18mm x (H) 90mm x (D) 72mm. The weight is 65 g. The operating temperature is from -5°C to + 55°C. The storage temperature is from -40°C to + 70°C.
