AC Current Sensor with Modbus Support and Clamp-Type CT (up to 630A)
PAL-Plus Sensor High-Capacity Model | Hexacore Corporation
Compact IoT Sensor with Built-in Modbus RTU Communication for Circuit-Level AC Current Measurement (125–630A)
PAL-Plus High-Capacity Model: IoT Sensor with Built-in Communication for AC Current Measurement We offer four sensor models supporting rated currents of 125A, 250A, 400A, and 630A. Key Features: Modbus RTU Communication Highly versatile and easily integrated into existing systems. Split-Type Clamp Sensor Enables safe and easy installation without stopping equipment operation. Ultra-Compact Design with Built-in Communication Ideal for installations with multiple measurement points, saving space and simplifying setup. Combine with the PAL-Plus Gateway, which converts sensor signals to Modbus TCP and supplies power to sensors, for a more space-efficient and cost-effective system configuration. For more details, please download the brochure or contact us. Demo units are available upon request. For small and medium-capacity sensors (up to 60A), please refer to the PAL-Plus product page.
