PROBLEM TO BE SOLVED: To provide a driving device for control equipment capable of supplying the basis of opening failure detection in another system while keeping one system on concerning a driving device for AC double system control equipment. SOLUTION: Concerning this driving device for control equipment, first and second circuits 11 and 2 are connected in parallel, one of two nodes constitutes an AC power source connecting terminal T1 and the other node constitutes a control equipment connecting terminal T2. In the first circuit 1, a first rectifier 11 and a first driving element 12 are serially connected. The first rectifier 11 is directed so that a current Ia can flow from the terminal T1 to the terminal T2. In the second circuit 2, a second rectifier 21 and a second driving element 22 are serially connected. The second rectifier 21 is directed so that a current Ib can flow from the terminal T2 to the terminal T1.
