<p><P>PROBLEM TO BE SOLVED: To shorten a connection from a terminal base as an input portion to a primary side of an internal transformer and to satisfy overcurrent resistance, thereby improving operation efficiency by preventing the mistake of wiring. <P>SOLUTION: A current input converter 13 insulates an input current, received by the terminal base, converts it into a predetermined analog signal by transformer 14, and converts the analog signal, obtained by the transformer 14, into a digital signal by an A/D converting circuit. The terminal base of the current input converter and one end of primary winding of the transformer are connected to each other by a first metal plate and a second metal plate which are in fixed shapes, and the first metal plate in the fixed shape has one end fitted to the terminal base and the other end fitted to the one end of the primary winding of the transformer. Further, the second metal plate in the fixed shape has one end fitted to the terminal base and the other end fitted to the other end of the primary winding of the transformer, and the terminal base and the other end of the primary winding of the transformer are connected to each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
