PURPOSE:To obtain an inexpensive and small-sized device by switching a data displayed on a digital indicator by a display switching key, monitor-displaying it, and displaying it by one indicator. CONSTITUTION:A detecting signal from a sensor part 7 of a temperature, etc., and a set data by a program key in a key matrix circuit 1c are read in a microcomputer 4, they are compared, and by controlling the microcomputer, relays 3a-3d of an output relay part 12 are driven and controlled. A digital indicator 2 is provided on this microcomputer 4, and a time and timer display, etc. are executed. A display switching key is provided so that a display to this indicator 2 is executed by switching a data from the microcomputer 4, and by switching this key, a part of each digit display element of the indicator concerned 2 is used, and an operation data of an output apparatus such as a relay, etc., an input signal from a sensor part 7, etc. are displayed. |
