Turnips RPT 258 (DC)
The relay consists of the following elements: time relay RV, intermediate relays 1RP having two windings - working (parallel) and restraint (consecutive), capacitors C, and C, resistors 1R1, 1R2, 1R3, 1R4, 1R5 and forefinger relay RO and RW.
Relay RPT 258 in its construction and principle of operation is substantially similar relay RPT 58.
For the implementation of the first cycle AR is used to temporarily break contact element time RV, and the second is the main time delay contact.
The relay is performed at the nominal voltage of 110 V and 220 V and currents retention sequential winding of 0.25; 0.5; 1; 2.5 and 4 and.
When selecting the performance of the device rated current holding successive winding of the relay 1RP should be less than the rated current of the retractor winding of the contactor switch is turned on. For example, at the rated currents of the windings of the contactors pull in the range of 0.3 to 0.6 and 0.6 to 1.2 a, 1.2 to 3 and so on rated current holding successive winding of the relay 1RP should be taken accordingly 0,25; 0,5; 1 and so on
At nominal voltage and ambient temperature of 20° C and relative humidity not more than 80% of the charging time of the capacitor to a voltage required for the intermediate relay 1RP (ready relay to the re-action) is in the range of 60-100 sec (when the set value is temporarily closing relay contact time 1-9 seconds)
When the change of the ambient temperature from -20 to +20° C, the charging time of the capacitor is different from that at an ambient temperature of 15-25° C not more than 12 seconds while changing the ambient temperature from 20 to 40 With no more than 8 seconds.
At an ambient temperature of +20° C, the device clearly works when 0,8 UN, and the charging time of the capacitor to a voltage necessary for operation of the relay 1RP, increased to 4 minutes by removing the voltage from the parallel winding of the relay 1RP anchor it is held in attracted position when the current flowing through the serial winding equal to IR.
The power consumed by the sequential relay coil 1RP when In not more than 1.2 watts.
