What is a Monitoring / Measuring Relay?
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.
Types of Monitoring Relays Available?
? Motor protection relays
? Temperature monitoring relays
? Water level control relays
? Voltage
? Current

Omron K8DT 系列控制繼電器
Omron K8DT 測試和監(jiān)控繼電器是面板理念價值設(shè)計的一部分，該理念可控制面板設(shè)計，并使制造符合全新標(biāo)準(zhǔn)。 K8DT 系列可保護(hù)重要設(shè)備使用各種符合國際安全標(biāo)準(zhǔn)的測量和監(jiān)控繼電器時免受傷害。 低功耗和低熱量設(shè)計可提供更長的工作壽命。
節(jié)省空間
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(xì)長型主體使空間內(nèi)可以安裝更多與控制面板同等大小的設(shè)備，從而增加控制面板的功能。
推入式接線端子
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(tài)和絞合電線或套圈。
