A monitoring / measuring relay is a protective control device, various types are available suiting what you wish to monitor. The relays receive input signals then monitor them and then output an alarm signal when a set value is reached (alarm relays). The relays protect your equipment against over voltage and over current faults. Monitoring relays monitor AC power supplies, voltage and current, analogue signals detecting unusual activity in equipment against set alarm thresholds.
? Motor protection relays
? Temperature monitoring relays
? Water level control relays

Omron K8DT 測試和監控繼電器是面板理念價值設計的一部分，該理念可控制面板設計，并使制造符合全新標準。 K8DT 系列可保護重要設備使用各種符合國際安全標準的測量和監控繼電器時免受傷害。 低功耗和低熱量設計可提供更長的工作壽命。
K8DT 系列通過降低布線管道和頂板空間之間的寬度，有助于縮小控制面板尺寸。 細長型主體使空間內可以安裝更多與控制面板同等大小的設備，從而增加控制面板的功能。
所有 K8DT 繼電器上的推入式接線端子塊可減少布線所需的時間和工作量。 推入式接線端子使得無需工具也可插入帶引腳接線端子的固態和絞合電線或套圈。
