Document Type and Number:
WIPO Patent Application WO/2019/073856
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve fast safety response performance. A safety controller (100) comprises a first voltage monitor circuit (12) and a second voltage monitor circuit (22). The first voltage monitor circuit (12) is an AD converter which operates by receiving electric power from a second power supply (21) and which transmits to a second MPU (20) a signal notifying the occurrence of an anomaly in a first voltage value. The second voltage monitor circuit (22) is an AD converter which operates by receiving electric power from a first power supply (11) and which transmits to a first MPU (10) a signal notifying the occurrence of an anomaly in a second voltage value.
