Document Type and Number:
Japanese Patent JP7420656
Kind Code:
B2
Abstract:
To provide a relay output control device improving the safety.SOLUTION: In a relay output control device 1, a control unit 10 determines failure based on contact checking signals OUTRAS and OUTRBS of a contact of an output relay OUTR input from a check input circuit 22 and a detection signal OPWS in an open/close state of a switch SW2 input from a sensor 24.
