Applications

The CR4395-EL-120-660-X-CD-ELR-I can be used in a variety of applications, such as industrial automation, energy management, process control, and others. It can be used to monitor, compare, and control voltage, current, frequency, power, and other signals. It is suitable for monitoring AC/DC signals, as well as AC single/three phase signals. It can also be used for waveform recording and logging.

In industrial automation, it can be used to monitor and control motors, pumps, fans, and other machinery, as well as providing an indication of overload, overvoltage, or undervoltage conditions. It can also be used to detect contactors or phase reversal faults.

In energy management systems, the monitor can be used to control demand side and on-site energy storage. It can also be used for energy loggers and charge controllers. Additionally, it can be used for monitoring power quality and performing energy audits.

In process control, the monitor can be used to adjust process parameters and keep systems within desired ranges. It can be used to detect system faults and malfunctions, as well as performing periodic analytics. Additionally, it can be used for logging process events.

Working Principle

The CR4395-EL-120-660-X-CD-ELR-I works by monitoring voltage, current, frequency, power, and other signals. The signals are received and converted into electrical signals, which are then analyzed and compared to preset thresholds or limits. If the threshold or limit is exceeded, an alarm is triggered, and an isolated relay is activated.

The monitor can be programmed to respond to two independent alarm thresholds, providing two isolated relays. The response time of the monitor is adjustable from 0.2s to 10s, allowing for rapid response in an emergency. Additionally, the monitor can be programmed to operate in two different modes – single threshold mode or dual threshold mode.

In single threshold mode, the monitor responds to a single alarm threshold. It monitors the value of the monitored signal and activates an alarm and, if necessary, an isolated relay when the monitored threshold or limit is exceeded. This mode is suitable for applications where only one threshold needs to be monitored.

In dual threshold mode, the monitor monitors two independent thresholds. It monitors the value of the monitored signal and activates an alarm and, if necessary, an isolated relay when either of the monitored thresholds or limits is exceeded. This mode is suitable for applications where two independent thresholds need to be monitored.

The CR4395-EL-120-660-X-CD-ELR-I is highly programmable, allowing for custom monitoring and control solutions. The monitor can be programmed to operate in multiple modes, allowing for a variety monitoring of signals. Additionally, the monitor provides two isolated relays for alarm indication and control.

Conclusion

The CR4395-EL-120-660-X-CD-ELR-I is a compact monitor designed for monitoring voltage and current signals. It is highly programmable, making it an ideal choice for a wide variety of applications, including industrial automation, energy management, and process control. It can be programmed to respond to two independent alarm thresholds, providing two isolated relays, and its response time is adjustable. This makes it an ideal choice for monitoring and controlling various signals.
