CONTROL UNIT

PROBLEM TO BE SOLVED: To provide a degree of flexibility in layout within a distribution panel, by preventing an operation display face from being reversed, even when being rotated in the installation direction by 180 degrees. SOLUTION: A control unit has a main unit 1 which consists of a first case 11; an input/output terminal part 12 prepared at the right end of the first case 11; a signal processing section 12 electrically connected to the input/output terminal part 12, and a first connector 14 electrically connected to the signal processing section 14; and a sub unit 2, which consists of a second connector 21 which is removably installed on the first connector 14 and electrically and mechanically connected to the first connector 14; and an operation display portion 22, which consists of a display portion 241 and an operation portion 242 and is formed on the front surface of the second case 23. The first and second connector 14, 21 are formed mutually connected, without having to change the installation direction of the sub unit 2 to the distribution panel, even when the right end of the first case 11 turns either to the right or to the left.
