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 系列控制继电器
Omron K8DT 测试和监控继电器是面板理念价值设计的一部分，该理念可控制面板设计，并使制造符合全新标准。 K8DT 系列可保护重要设备使用各种符合国际安全标准的测量和监控继电器时免受伤害。 低功耗和低热量设计可提供更长的工作寿命。
节省空间
K8DT 系列通过降低布线管道和顶板空间之间的宽度，有助于缩小控制面板尺寸。 细长型主体使空间内可以安装更多与控制面板同等大小的设备，从而增加控制面板的功能。
推入式接线端子
所有 K8DT 继电器上的推入式接线端子块可减少布线所需的时间和工作量。 推入式接线端子使得无需工具也可插入带引脚接线端子的固态和绞合电线或套圈。
