Abstract
The present invention achieves high speed safe response performance. A safety controller () includes a first voltage monitoring circuit () and a second voltage monitoring circuit (). The first voltage monitoring circuit () is an AD converter which operates upon receiving electric power from a second electric power source () and which transmits, to a second MPU (), a signal that gives notification of occurrence of an anomaly in a first voltage value. The second voltage monitoring circuit () is an AD converter which operates upon receiving electric power from a first electric power source () and which transmits, to a first MPU (), a signal that gives notification of occurrence of an anomaly in a second voltage value.
