Document Type and Number:
Japanese Patent JP7047739
Kind Code:
B2
Abstract:
Provided is a relay state determination device capable of accurately determining whether or not a relay has deteriorated. A relay state determination device (10) includes a voltage value acquisition unit (22), a contact bounce time acquisition unit (28a), and a state determination unit (28b). The voltage value acquisition unit (22) acquires a voltage value between one pair of contacts (4b1 and 4b2) mutually opened and closed in a relay (4). The contact bounce time acquisition unit (28a) obtains a contact bounce time (Tb) indicated by the one pair of contacts (4b1 and 4b2) based on the temporal change in the voltage value after the ON instruction to the relay (4). The state determination unit (28b) compares the contact bounce time (Tb) with a time threshold value (Tth) to determine whether or not the relay 4 has deteriorated.
