Monitor - Current/Voltage - Relay Output

The EISNNOA50A Monitor is a specialty monitoring relay designed to provide protection and monitoring for current/voltage applications. It offers a comprehensive range of features, with up to eight inputs and two relay outputs to provide both trip and status operations. The device offers a wide range of possible settings, including adjustable trip ratios, start-up delay times, and minimum alarm times.

The EISNNOA50A Monitor is an ideal choice for applications such as switchgear monitoring, busbar protection, generator protections, and portable power monitoring. It can be used in a wide variety of applications, including in industrial, commercial, and residential spaces. The device is also well suited to be used in hazardous locations, as it is UL and IEC approved for such environments.

Working Principle

The EISNNOA50A Monitor works by measuring the current or voltage level at the load. When the current or voltage exceeds the set trip ratio, the monitor sends a signal to the relays to open or close. This signal can be used to disconnect the load, shut down the system, or sound an alarm. The device also has other protection functions, such as overload protection, high current/voltage protection, and high frequency protection.

The EISNNOA50A Monitor also has a unique start-up delay setting, which allows the system to ramp up or down gradually, preventing any sudden power interruptions. The adjustable trip ratio and minimum alarm time settings allow users to configure the device to suit their application needs. This ensures that the system will remain safe and reliable, even in the most demanding environments.

Conclusion

The EISNNOA50A Monitor is an ideal choice for current/voltage applications. Its wide range of settings and advanced features make it an ideal choice for applications such as switchgear protection, busbar protection, generator protection, and portable power monitoring. With its UL and IEC approval, the device is suitable for hazardous areas as well.
