This iRTMF is a Time delay relay. The time delay range is from 0.1s to 100h. It allows on of the four types of time delay to be selected A, B, C or H. The Uc control and power supply voltage is from 12VAC to 240VAC +/-10% and 12VDC to 240VDC +/-10%. Depending on the choice the iTRMF generates time delay cycles for iRTA, iRTB, iRTC or iRTH relays. 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 0.33A 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.
