Intermediate reed relay series RPG-3


The relay intermediate reed switches series RPG-3 are designed for operation in automation and control circuits made on printed circuit boards, for 12 and 24VDC supply voltage, rectified three-phase current with a ripple frequency of at least 300Hz without the use of a filter, as well as rectified current with a filter , Providing a ripple of not more than 6%.

Relays are suitable for operation in control systems based on microprocessor technology and are component parts.

The power consumption of the relay winding in the cold state corresponds to the data in Table. 2.


The insulation resistance of the relay types RPG-3-2301 and RPG-3-2302 corresponds to row 1, type relay RPG-3K2301 and RPG-3K2302 - row 2.

The parameters of the electrical circuits switched by the contacts, and the switching wear resistance of the relay contacts, depending on the application category for the modes of normal commutations, correspond to those indicated in Table. 3.


When commutating inductive and capacitive loads, as well as in the operation of incandescent glows, contact protection is carried out in accordance with the requirements of OST 11.0152-85.

The warranty period of storage of the relay is 3 years from the date of manufacture.

The warranty period of the relay operation is 2 years from the date of commissioning.

Warranties on the relay are removed after 5 years from the date of manufacture.


The relay is a device whose main elements are the coil (Figure 1) and the reed switches located in it.

Conclusions of reed switches and coils are soldered to lamellas. The distance between the lamellas is a multiple of the step equal to 2.5 mm. The coil covers the screen, designed to increase the sensitivity of the relay and to protect against the influence of external magnetic fields. The relay is closed with a cover.
