PURPOSE:To understand easily the output state of the signal delivered to a terminal by setting a switch terminal opposite to a display part where the switching actions are displayed in a pattern. CONSTITUTION:A timepiece device 26 counts the time and sets the output time points of each relay 28 by means of a setting key 13. These time points are supplied to a CPU23 and stored in a prescribed area of a RAM25 together with the identification codes of each relay 28. The timer output is controlled by the CPU23 for each relay 28. When no timer output is produced at each relay 28, a contact symbol 22 at an action display part 17 of a display part 17 corresponding to the relay 28 shows an OFF state where a contact A is opened. When the timer output is given to the relay 28, said symbol 22 shows an ON state where a contact B is short-circuited for control. Thus the timer output state can be known easily with each terminal on a terminal stage just by reading the open/close state of the symbol 22 of the part 17. |
