    Abstract: A relay device includes a coil portion, a fixed contact, a spring, a moving contact and a drive circuit. The drive circuit controls the electromagnetic force of the coil portion to be a first electromagnetic force when switching the fixed contact and the moving contact in a contact state to a non-contact state. The drive circuit controls the electromagnetic force of the coil portion to be a second electromagnetic force that is larger than the first electromagnetic force after a lapse of a first time from start of control of the electromagnetic force of the coil portion to be the first electromagnetic force. The drive circuit controls the electromagnetic force of the coil portion to be reduced with time after a lapse of a second time from start of control of the electromagnetic force of the coil portion to be the second electromagnetic force.

    Abstract: A method in a control unit for closing a contactor device. The control unit is configured to enable the movement between the closed and opened position by energizing a coil of an electromagnetic circuit. The method includes applying a voltage over the coil; determining, during a first period of time, current through the coil and voltage over the coil and estimating based thereon model parameters for a model predicting the behavior of the current through the coil if the contactor device were to stay in an open position, and measuring, after the ending of the first period of time, current through the coil and determining a difference between, on the one hand the measured current and, on the other hand a predicted current of the model, and repeating the measuring and determining until a state change from open position to closed position is detected by the difference in current.

    Abstract: An electromechanical switching circuit comprises an integrated circuit (IC) having an input terminal, an output terminal and a control terminal. The IC is arranged based on a voltage transition at the control terminal, sampling the voltage level at the input terminal and supplying it at the output terminal. The output voltage level is maintained at the output terminal until a voltage transition at the control terminal. A control circuit connected to the control terminal includes a first monostable switch whose actuation causes a voltage transition at the control terminal so the voltage level applied at the input terminal is supplied at the output terminal. An output circuit includes a second, electromechanical, monostable switch whose contacts are moved to their unstable state in response to a first voltage level at the output terminal and allowed to resume their stable state in response to a second voltage level at the output terminal.

    Abstract: A driver circuit and a diagnostic method are provided. The driver circuit includes a first voltage driver, a second voltage driver, and a microprocessor. The microprocessor generates a first pulse width modulated signal to induce the first voltage driver to output a second pulse width modulated signal to energize a contactor coil. The microprocessor sets a first diagnostic flag equal to a first value if a first filtered voltage value is greater than a first threshold value. The microprocessor sets a second diagnostic flag equal to a second value if a first filtered current value is less than a threshold value. The microprocessor stops generating the first pulse width modulated signal to de-energize the contactor coil if the first and second diagnostic flags are set equal to the first and second values, respectively.

    Abstract: A potential of an end of the coil is inputted to a plate-OFF detecting portion which detects OFF-tendency in which a plate of a relay is about to get apart from a head of a core of the relay. When the OFF-tendency is detected, a coil current for supplying a coil of the relay is set to a first current value with which a plate of an electromagnetic relay is drawn and a movable contact of the relay comes in contact with a fixed contact of the relay. When an external disturbance ends, the coil current is returned to a second current value, which is smaller than the first current value, so that the movable contact and the fixed contact are kept in contact with each other.
