<p><P>PROBLEM TO BE SOLVED: To provide a network environment monitoring device for extending analog input terminals, and for increasing/decreasing the number of terminals as necessary. <P>SOLUTION: The back face of a network environment monitoring device 1 is provided with one terminal 8 for communication. Also, a plurality of analog input terminals 5 are integrated into a unit, and this terminal unit 6 is provided with two terminals 7 for communication. One end of a communication cable 9 is connected to a terminal 8 for communication of a network environment monitoring device 1, and the other end is connected to one terminal 7 for communication of the terminal unit 6. A sensor 2 or the like can be connected to the analog input terminal of the terminal unit 6. Also, one end of the communication cable 9 is connected to the other terminal 7 for communication of the terminal unit 6, and the other end is connected to the terminal 7 for communication of the terminal unit 6 in order to extend the other terminal unit 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
