Expand the monitoring points gradually according to the required number of circuits. Supports multi-circuit monitoring for up to 31 units and a maximum distance of 100m.

In monitoring multi-circuit equipment, it is important to design with not only the current number of monitoring points in mind but also future expansions. The PAL-Plus large-capacity version, in combination with the PAL-Plus unit, allows for the bulk collection of numerous current data. Up to 31 sensors can be connected to a single unit, and the wiring length to the final stage can accommodate up to 100 meters. Additionally, it is possible to configure a connection between the Modbus RTU on the sensor side and the Modbus TCP on the upper side. Monitoring points can be gradually increased in line with equipment expansion. 【Challenges】 - Efficiently monitor numerous circuits - Prepare for future expansions - Organize the overall system conditions 【Expected Benefits】 - Bulk monitoring of multiple currents - Expansion up to 31 units - Integration from Modbus RTU to Modbus TCP You can consider configurations ranging from small-scale to multi-point setups for main and branch circuits or multi-circuit panels. This can also be utilized for configuration confirmation before implementation, design during the addition of monitoring points, and planning for future expansions. Please take a look at the materials. For actual configuration conditions, please contact us individually.
