PROBLEM TO BE SOLVED: To provide a relay end-of-service-life forecasting device that can accurately forecast the end-of-service-life of an electromagnetic relay.SOLUTION: By diagnosing the life of a relay 10 based on the time from when the application of power to the relay 10 is started or when the application of power to a relay coil is stopped by a control unit 2 till when the actual opening or closing of the relay 10 is detected, the end of the service life of the relay 10 can be accurately forecasted without a remarkable decline in forecasting accuracy due to the effects of load conditions and environmental conditions. Specifically, forecasting the end of the service life of the relay 10 based on time, increases the forecasting accuracy because time is a value that is not affected by the external environment. In addition, the end of the service life is forecasted based on the actual opening/closing of the relay 10, a fault in the relay 10 can be immediately detected, but at the same time, the effects due to individual differences can be eliminated, resulting in accurate forecasting of the end of service life of the relay 10. |

PURPOSE: To simplify the configuration by incorporating an unit for determining a failure due to additional operating conditions, a statistic operational data and a maintenance instruction, and an operational display for designating these data.
CONSTITUTION: When keys 24, 25 on a wire 26 are depressed simultaneously, a slide key 12 is released in a functional plane. Consequently, a corresponding functional group is selected by depressing the slide key 12. When the release key 24 is depressed again at an output function 27, for example, a control function is obtained. A stored control function is called back by depressing the release key 24 again and delivered to a memory. Consequently, a corresponding transfer can be made at a functional block 28. Other blocks (not shown) simply have a role of designation. More specifically, when a designation block is reached by depressing the release key 24 from designation of state, the operation can be shifted simply to diagnosis by means of a forward slide key 12.
