Abstract:
PURPOSE:To attain an inexpensive device whose maintenance and inspection are simplified by storing preliminarily display patterns or the like in a memory part and generating these patterns with a selecting switch or the like. CONSTITUTION:A display pattern due to a no-voltage contact 1, a display pattern due to a selecting switch 21, and an excitation pattern with which a relay coil 24 is excited are set and stored preliminarily in a memory part 32. The switching signal from the no-voltage contact 1 is inputted to an operating part 33 through an input part 31. The display pattern in the memory part 32 is selected by this operating part 33 to light indicators 2 with a prescribed pattern through the first output part 34. The selecting switch 21 is switched in accordance with this lighting to select the display pattern and the excitation pattern in the memory part 32, and the control state is displayed on indicators 2 through the first output part 34, and the relay coil 24 is excited or degaussed through the second output part 35, thus controlling a plant.
