Abstract

PURPOSE: To stabilize the operation of a lead relay, by causing the variation of a power voltage when a power supply is cut off to fall gradually.
CONSTITUTION: By a timing signal inputted from terminal 1, switching circuit 12 is operated and power driver circuit 8 is also driven to output a driving pulse signal from circuit 8. This signal is voltage-amplified by voltage amplifier circuit 9 to obtain a voltage level required to drive magnetic holding type relay 3. Using a driving pulse signal with the voltage level, integral circuit 10 alllows the trailing edge of the pulse of the driving pulse signal to fall gradually by adjusting, and the signal is current-amplified by circuit 11 to obtain a relay-driving pulse signal, thereby driving relay 3.Being viewed from relay 3, this is equivalent to the ON-OFF operaton of the power supply. The operation can therefore be stabilized by suppressing the mechanical vibrations of the relay contact.
