Smart Power Visualization for Every Equipment with Modbus-Compatible IoT Sensor to Accelerate Energy Savings
The “PAL-Plus typeE” is an IoT sensor equipped with a built-in communication function that enables simplified cumulative energy measurement. It supports five sensor models for rated currents of 60A, 125A, 250A, 400A, and 630A. This solution provides a cost-effective and simple way to visualize power consumption for each facility. Key Features High Compatibility: Utilizes the Modbus RTU communication protocol, ensuring excellent versatility and easy integration with existing systems. Non-Stop Installation: The split-clamp sensor design allows safe and simple installation without halting equipment operation. Compact Design: Built-in communication functionality enables ultra-compact sensors, making installation easy even when multiple measurement points are required. About Simplified Measurement Based on preset voltage and power factor values, the sensor calculates simplified cumulative energy and power from the measured current. It also outputs cumulative current values, providing consistent reference data for energy management. Compatible with single-phase two-wire and three-phase three-wire systems. For three-phase systems, calculations are based on a balanced circuit. For more details, please contact us.

What is the PAL series sensor that can do more than just measure?
It may look like an ordinary sensor at first glance... but it's actually different!! We have uploaded a page introducing the "PAL Series Sensor," which integrates communication functions into the sensor itself, allowing both "measurement" and "communication" to be completed with just this one device. | PAL Series Sensor Measurement Items | - PAL-Plus / PAL-Plus Large Capacity Version: AC Current - PAL-Plus typeE: Simple Integrated Electric Energy, Simple Power, etc. - PAL-Temp: Temperature and Humidity As electricity costs rise and efforts towards SDGs are strengthened, this product serves as an excellent stepping stone for "visualization," so please take this opportunity to check it out! Additionally, we also accept proposals for system configurations utilizing the PAL Series Sensors. If you have any concerns regarding visualization for your factory or equipment, feel free to consult with Hexacore.
