作する複数のカウンターと、これらカウンターの
接点とを、夫々現場側の検出回路と、中央側の受
信回路とに設け、両側のカウンターをパルス信号
が送信されるカウントアツプ用ケーブルで接続す
ると共に、前記検出回路側のカウンターの各接点
と直列に故障要素別の接点を接続し、これら接点
を故障検出用ケーブルを介して受信回路側の前記
カウンターの接点と接続し、これら各接点に故障
要素の状態を中央側で検出する受信リレーを夫々
接続したことを特徴とする故障検出回路。 A plurality of counters that operate when the pulse signal reaches a specified constant and contacts of these counters are provided in the detection circuit on the field side and the reception circuit on the center side, respectively, and the counters on both sides are set up when the pulse signal reaches a specified constant. At the same time, connect contacts for each fault element in series with each contact of the counter on the detection circuit side, and connect these contacts to the counter of the reception circuit side via the fault detection cable. What is claimed is: 1. A failure detection circuit, which is connected to a contact and is characterized in that a receiving relay is connected to each of these contacts for centrally detecting the state of a failure element.
