IMPULSE electromagnetic relays on the reed switch

摘要

Pulsed electromagnetic relay reed switch relates to a railway automation and is intended for use as a receiver in pulse interval regulation circuits rail system trains, i.e. automatic lock. Further comprises a second diode-resistor-capacitor chain, the second electronic key, fourth and fifth display chain, a voltage converter unit inclusion of heating, the connection of the supply inputs to the outputs of the voltage converter is one of the outputs of the second electronic switch is connected through the heating element with one of the inputs voltage converter and one of the terminals for the power supply of the heating element, the other terminal to connect the power supply of the heating element ment is connected to another input of the voltage converter and the other output of the second electronic switch, the output of the first electronic switch is connected to the input of the time delay block. Achieved by increasing the reliability of the relay operation and auto-lock, to inform staff about the origin predotkaznogo state, eliminating the need for seasonal switching on and off of the heating element, as well as reduced power consumption by controlling the temperature inside the relay and the automatic heating control. 1 n.
