| High-capacity AC current sensor | Easy visualization with clamp-type sensor |

| High-capacity AC current sensor | Easy visualization with clamp-type sensor |

IoT sensor with built-in communication function that supports Modbus RTU communication, easy to use, space-saving, and capable of measuring AC current for each circuit (125~630A).

The "PAL-Plus Large Capacity" is a large-capacity IoT sensor with built-in communication functions that can measure alternating current. We offer four sensors that support rated currents of 125A, 250A, 400A, and 630A. 【Three Key Points】 1. By adopting the Modbus RTU communication protocol, it boasts excellent versatility and can be easily integrated into existing equipment. 2. As a split clamp-type sensor, it can be safely and easily installed on existing equipment without stopping its operation. 3. By incorporating the communication function within the sensor, we have achieved ultra-compact design, allowing for easy installation even when there are many measurement points. By combining it with the "PAL-Plus Unit," a gateway that has a signal conversion function to convert the sensor's signal to Modbus TCP and a power supply function for the sensor, it enables the construction of a more space-saving and cost-effective system! For more details, please download the materials or feel free to contact us. We also have rental units available. | If you are looking for small to medium capacity sensors up to 60A, please refer to the "PAL-Plus" product page |
