| Abstract: | In this paper the DZO 2 intrinsically safe telephone coupling device, gets rid of disadvantages of the former DZO 1. It can be applied to the change of power voltage and operates normally at 10 to 70 volts. The circuit has advantages such as less components,lower cost,better and reliable and easier realization. It is a new kind of design method. |
