Claims

[Claims for Utility Model Registration] A device 5 for sequentially turning on power to a plurality of devices 2 to 4 and turning off the power in the reverse order of the power-on order, comprising: On-delay timers ONT-1 to ONT-3, off-delay timers OFFT-1 to OFFT-3, and relay R for each control device 2 to 4.
L-1 to RL-3, each of the on-delay timers ONT-1 operates at a set time after the power switch SW is turned on, and the relay RL belonging to the corresponding power controlled device 2 operates.
The electric contact rl-1 inserted into the first power supply line L11 of -1 is closed, and when each relay RL-1 is energized, the electric contact rl-1 inserted into the power line PWL of the corresponding power controlled device 2 is closed. 1, and the on-delay timer O is connected to the first power supply line L21 of the relay RL-2 belonging to the next power controlled device 3.
The electrical contact rl-1 connected in series with the electrical contact ont-1 of the NT-1 is closed, and each off-delay timer OFFT-1 operates at a set time after the power switch SW is disconnected to turn off the corresponding power source. Open the electrical contact offt-1 inserted into the second feed line L12 of the relay RL-1 belonging to the control device 2, and further install an off-delay timer OFFT- in the second feed line L12 of the relay RL-1. The relay RL is connected in series to the electrical contact off-1 of 1.
-1's electrical contact rl-1 is connected in parallel with the electrical contact rl-2 of the next relay RL-2, and the on-delay timer and off-delay timer provided for each power-controlled device are operated. A power supply sequential turning on/off device characterized in that the order is set in an inverse relationship.
