Abstract

PURPOSE:To prevent transient actuation currents from being superposed by using power feed signals as actuation signals even when devices are put in parallel operation, by freely specifying delay times from the reception of the actuation signals to actual actuation. CONSTITUTION:This device is provided with a delay time specifying circuit 4 which can specify an optional delay time, a circuit 2 which delays an actuation signal 1 by the specified time, and actuation indication controlling circuit 6 which generates an actuation indication signal 7 indicating actual actuation from the actuation signal 1 and the output of the delay circuit 2. Therefore, the time from the reception of the actuation signal to the actual actuation start is specified freely.
