Abstract
A controlling device includes a controlling device main unit and a terminal block attached removably to the controlling device main unit. The terminal block is provided with first through Nth (N≧2) permanent magnet placement portions. The controlling device main unit includes first through Nth magnetism detecting portions that, in a state wherein the terminal block is attached, are positioned in positions in proximity to the first through Nth permanent magnet placement portions, to detect the respective magnetism of the permanent magnets that are placed selectively in the placement portions. The controlling device further includes a terminal block type identifying portion that identifies a type of terminal block attached to the controlling device main unit based on detection signals, indicating whether or not there is magnetism, from the first through Nth magnetism detecting portions.
