Summary: | The first circuit section 10A requiring protection of its withstand voltage and the second circuit section requiring no protection of its withstand voltage are provided in a separated structure. The output terminal of the first circuit section 10A and the input terminal of the second circuit section 10B are provided as external terminals. Where intrinsic safety is not required, the two external terminals are directly connected outside the LSl. On the other hand, intrinsic safety is required, in place of the first circuit section 10A, an excess voltage suppressing circuit is connected to the front stage of the second circuit section 10B. |
