Title:
RELAY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022152619
Kind Code:
A
Abstract:
To control a plurality of photo relays individually with a small number of control lines.SOLUTION: A relay control device has: N (N is a natural number) photo relays; two pulse generators; and an N-stage nonlinear LC ladder circuit connected between the two pulse generators. A circuit in which a resistor, a lamp, and a DC power supply are connected in series is connected in parallel with a varicap diode in each stage of the N-stage nonlinear LC ladder circuit. The lamps control opening/closing of the photo relays.SELECTED DRAWING: Figure 6
