Introduction

The K8AB-TH11S AC/DC24 is a highly reliable current/voltage monitor relay with output characteristics designed to provide safe, accurate and reliable protection for AC/DC24 systems. This monitor is designed for applications that require precision monitoring and protection capabilities, such as, circulators, variable frequency drives, motors, transformers, converters, and other AC/DC24 systems.

Application Field

The K8AB-TH11S AC/DC24 monitor is designed to provide current/voltage monitoring and protection for AC/DC24 systems. This monitor is ideal for applications that require high accuracy and precision monitoring and protection, such as, centrifugal motors, variable frequency drives, transformers, converters, and other AC/DC24 systems. The K8AB-TH11S AC/DC24 monitor is designed to help protect against over/under loading, short circuits, and phase loss.

Working Principle

The K8AB-TH11S AC/DC24 monitor operates on an analog current/voltage/temperature sensing principle. It uses an isolated current/voltage sensing circuit that allows detection of an over/under loaded condition, a short circuit, or a phase loss. The relay\'s output stage is designed to automatically switch off the monitored AC/DC24 circuit, when an overload, short circuit, or phase loss is detected.The current monitoring input circuit is designed to provide precise current measurements through a resistive current sensing element. The voltage input circuit is also designed with precise voltage measurements in mind, with the help of a resistive voltage divider. The K8AB-TH11S AC/DC24 monitor is provided with a temperature sensing input to detect excessive temperature of the monitored AC/DC24 circuit.

Safety Features

The K8AB-TH11S AC/DC24 monitor has an advanced safety feature, it has a fail-safe circuit that will automatically cut off the output in the event of a short circuit or over/under loading. The safety of the monitored AC/DC24 circuit is further ensured by a time delay function, which will delay the output of the monitored circuit if the monitored channels are dangerously loaded, short circuited or phases have been lost. The relay also provides an indication LED which will flash when the monitored circuit is overloaded, short circuited, or a phase has been lost, in order to easily detect faults in the monitored AC/DC24 circuit.

Conclusion

The K8AB-TH11S AC/DC24 is a highly reliable current/voltage monitor relay. It is designed to provide precision current and voltage detection with current sensing elements and resistive voltage dividers. It also has an advanced safety feature which provides for fail-safe operation in the event of an overload, short circuit, or phase loss. The K8AB-TH11S AC/DC24 monitor is a great choice for applications requiring high reliability and protection in AC/DC24 systems.
