DEVICE FOR CONTROLLING ELECTROMAGNETIC RELAY AT TEST ON VIBRATING AND SHOCK STAND Russian patent published in 2017 - IPC H01H51/00 

FIELD: electricity.

SUBSTANCE: device contains two portable DC sources with a voltage of 27 V and a remote control with ten identical relay control channels. In each of the channels, there is a plug-in connector, five indicator lights, and three toggle switches. The light bulb is configured to control the supply of voltage to the relay coil. Two bulbs are configured to control the closed relay contacts (21-41, 22-42). Two bulbs are configured to control the open relay contacts. The toggle switch is configured to supply voltage to the relay coil and the light bulb (L1). The toggle switch (T2) is configured to apply voltage to the closed relay contacts and two light bulbs (L2), the toggle switch (T3) is configured to apply voltage to the open relay contacts and two light bulbs (L3). The power supply of the relay contacts and the bulbs (L2, L3) is made from a direct current source, and all the lamp bulbs are diode.

EFFECT: increasing the number of simultaneously tested relays to ten, increasing the reliability of the relay control and test safety, reducing the energy costs and the consumption of vibrating and shock stands.
