Auxiliary Relay
REP-20


REP-20 - auxiliary relay
REP-20

The relays are intended for the switching of the loads in the electrical circuits of the control, protection and automation and also in the control circuits by electric drives with AC voltage up 380 V (50 Hz), 440 V (60 Hz), DC voltage up 220 V.

The environment is an industrial one which doesn’t contain the dust in the concentration breaking operation of the relay.

The relay mounting is carried out in different ways: for example, by means of a contact connector receptacle, screws on a panel, on a DIN-rail or without receptacle with soldering.

The range of the working temperature: - 50 °С … + 55 °С.

Relative humidity must be not more than 98% at a temperature of + 35 °C.

These relays withstand vibration in the range of the frequencies 0,5 – 100 Hz with an acceleration of 1g, and in the range of the frequencies 5 – 15 Hz with an acceleration of 3g.

Such relays are installed on the ships (under control of the Maritime register of shipping ) and keep working capacity:
а) in the conditions of vibration with the frequencies of 2 - 80 Hz:
          (2 - 13,2) Hz with a movement amplitude ± 1 mm;
          (13,2 – 80) Hz with an acceleration of  ± 0,7 g;
b) in case of beats with an acceleration ± 5 g and frequencies from 40 to 80 beats per minute;
c) at a long inclination of the vessel to 15 ° and a trim to 5 °, and also at rolling motions to 22,5 ° with the period of 7-9 seconds and ship pitching to 10 ° from a vertical;
d) in the conditions of relative humidity of air (75±3) % at a temperature plus (45±2) °C or (80±3) % at a temperature plus (40±2) °C, or (90±3) % at a temperature plus (25±2) °C.

Power consumption, not more than:
          for DC relay - 4 W;
          for AC relay - 7 VA.

Modifications according to contact group (1 figure – the number of make contacts , 2 figure – the number of break contacts):
          REP-20-80, REP-20-62, REP-20-44, REP-20-42, REP-20-24, REP-20-22.

Rated current of the contacts - 6 A.

Modifications according to rated voltage of the coil, V:
          direct voltage: 12, 15, 24, 27, 48, 60, 110, 220;
          alternating voltage with a frequency (50±1) Гц: 12, 24, 40, 110, 127, 220, 230, 240, 380, 400, 415;
          alternating voltage with a frequency (60±1) Гц: 12, 24, 40, 110, 220, 230, 240, 380, 440.

Rated voltage of the contacts: DC 12-220 В, АС 12-440 В.
The smallest rated current of contacts at a voltage of 12 V: 0,01 А.
Allowable limits of the supply voltage change Urated: 0,85 - 1,05.
Insulation test voltage: 2500 V.
Turning on time of the relay: not more than 0,03 s.

Resistance of isolation of the dry and pure relay which wasn't in operation, not less:
          in a cold state 50 МОм;
          in a heated state 10 МОм.

Weight of the relay, not more than:
          without receptacle – 0,18 kg;
          with contact connector receptacle - 0,3 kg.

Mechanical durability of the relay (cycles of switching on/switching off), not less:
          for AC 20х106;
          for DC 30х106.
