AC POWER CONTROL BOARD

PURPOSE:To simplify the mounting works and individual wirings of AC power controlling units, by making the AC power controlling unit, an input circuit breaker and a signal input-output part into one block, and by providing such a plurality of blocks inside an AC power control board. CONSTITUTION:In an AC power control board 1, a plurality of blocks 2a-2f are mounted on the main body of the control board 1, and in an adapter 11, a relay 12 and a terminal base 13 for external wirings are provided respectively. In the inner part of each block, an AC power controlling unit 3 having a displaying part 3a therein, an input circuit breaker 5 connected with the input of the AC power controlling unit 3, and an input-output part 7 for external connections are provided respectively. Thereby, wirings are made short, and wiring works are made easy, and further, the size of the control board 1 can be reduced. Also, the maintenance of the AC power controlling unit can be performed on the front surface of the control board 1.
