Title:
RELAY DEVICE
Document Type and Number:
Japanese Patent JPH0547280
Kind Code:
A
Abstract:
PURPOSE: To provide a noise-reduced constitution for a relay by giving a simple improvement to a circuit instead of giving a structural improvement.
CONSTITUTION: A relay 1, a pulse generating circuit 5, and a drive circuit 7 for giving a pulse drive power supply based on a pulse signal from the pulse generating circuit 5 to the relay 1 in the first transition and last transition of input signals for driving the relay 1, and giving a constant drive holding power supply between them are provided. When actuation of the relay is stopped, the suction force of the coil is restored instantaneously, and a suction/ removal speed of a movable member to the coil is reduced, thereby a collision noise by a relay action is reduced.
