Abstract

PURPOSE:To reduce the power consumption and interference by electromagnetic waves, by transmitting the signal enabled for the relay drive from the main operating panel only when the operating stage of load is changed to drive the relay. CONSTITUTION:When the operating state of load of terminal device is changed from the main operating panel, the terminal voltage data of the capacitor C is checked, and if it is charged, the relay drive pulse PD' is input to the relay drive stage 29 to drive relay r and to change the operating state of the load. On the other hand, if not charged, rapid charging signal is transmitted from the latch output section 28 to operate the rapid charging circuit 36 and the capacitor C is charged. Then, new data and relay drive enable signal are transmitted and the relay drive pulse PD is input to the relay drive section 28 to drive the relay r and to change the operating state of the load.
