Abstract
PURPOSE: To prevent noise at a unit power supply or break time or a trouble time from being transmitted to the signal bus, by supplying power to drivers belonging to the unit under a condition where the power supply of the unit is established.
CONSTITUTION: When voltages P1 and P2 are established and signal S1 becomes high-level, diode D1 is cut off, and TrQ1 and Q2 are turned on, and then, relay RL1 is operated to supply power to drivers DA1 to DAn. Consequently, noise of the internal circuit which may be generated in the transitional state of voltages P1 and P2 is prevented from being transmitted to the signal bus.
