Dual Independent Relay Outputs with Flexible Remote and Synchronized Control
The UbiBot® Metering Network Relay NR2 is equipped with two independent relay outputs, facilitating the flexible control of separate load devices via remote synchronized switching or individual point control. Each relay contact supports a maximum of 250V AC at 16A and is rated for a service life of 100,000 cycles, making it a robust solution for diverse load management applications.
High-Precision Energy Metering for Reliable Power Monitoring
The NR2 features built-in metering that tracks voltage, current, power, and cumulative energy consumption. Every kilowatt-hour is accounted for, providing full visibility into your power usage. Combined with the UbiBot App, you can access real-time energy data anytime, anywhere, making power management simpler and more efficient.
Smart Sensor Data Collection and Automated Device Linkage
The NR2 supports RS485 sensors and digital input acquisition, automatically uploading data to the platform at scheduled intervals. Devices can be controlled directly through the platform or linked with other devices within the platform, allowing seamless integration into complex applications while ensuring safe, efficient, and fully automated responses without the need for manual intervention.
Safety Interlock, Safety Control
The NR2 metering relay features configurable interlock protection that automatically deactivates one relay when the other is activated. This prevents both connected devices from being activated at the same time, reducing potential risks and protecting equipment integrity. It is especially suitable for motor forward and reverse control applications such as fans shutters and similar machinery.
Smart Control, Unwavering Reliability
The NR2 enables users to customize the default relay state upon power-up through the UbiBot IoT platform, offering options to retain the previous state, remain open, or close. This configurable behavior ensures the device returns to a safe and predictable condition after power interruptions, enhancing intelligent management and overall system reliability.
Input Wiring
Supports two switch inputs and can be connected to passive and active switches.
Output Wiring
Supports normally open or normally closed operations. Various wiring methods can meet different output requirements.
① Low Load Wiring: Suitable for non-resistive loads with a current of up to 5A, or resistive loads up to 16A.
② AC 220V Load Wiring: External load powered by AC 220V (metering unavailable in this configuration).
③ AC 380V (with Neutral) Load Wiring: The external load requires an AC 380V power supply with a neutral line. (metering is unavailable in this configuration)
An AC contactor or intermediate relay must be installed between the product and the load when any of the following conditions apply.
① Load rated voltage >250V AC
② Non-resistive load current >5A
③ Resistive load current >16A
Flexible Connectivity Options with The UbiBot® Metering Network Relay NR2 for Real-Time Control
The UbiBot Metering Network Relay NR2 integrates seamlessly with the UbiBot IoT Platform, offering WiFi, Ethernet (RJ45), and 4G connectivity for flexible deployment. It enables real-time remote monitoring and control of connected devices from any IoT-enabled terminal, including smartphones, tablets, and computers. Users have immediate access to device status and performance data for enhanced control.
