Claims (1)
ログラム暴走判定回路によりプログラム暴走を判定した
後、該制御装置が正常時にのみ制御出力パルスを出力す
べく、前記プログラム暴走判定に要する時間以上、前記
出力パルスを遅延させるように構成したことを特徴とす
る制御出力回路。In a control device using a microcomputer, after a program runaway determination circuit determines a program runaway, the output pulse is delayed for a period longer than the time required to determine the program runaway so that the control device outputs a control output pulse only when it is normal. A control output circuit characterized in that it is configured to
