PROBLEM TO BE SOLVED: To provide a control unit for electromagnetic relay, capable of more appropriately controlling an electromagnetic relay.SOLUTION: A relay control unit includes a control circuit 2a that computes external information, such as temperatures of a relay 6 detected through a temperature detection circuit 11, on-off states of other relays adjacent to each other, oscillation values detected by an oscillation sensor 4 and coil voltages monitored by a voltage monitor circuit 5 and changes control values of PWM control to the relay 6, on the basis of computed information. |
