Intermediate reed relay series RPG-3

GENERAL INFORMATION

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 structure of the conventional designation RPG-3X23XXXX:

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.

CONSTRUCTION AND PRINCIPLE OF ACTION

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.
