PATLITE (formerly Kasuga Electric) Wireless Data Acquisition System AirGRID(R) (Receiver) WDR-L-Z2

A system can be constructed even if new and old equipment and manufacturers are mixed.
Since it utilizes existing signal lights (with some restrictions), it can be introduced at low cost.
Equipment operation data can be collected automatically 24 hours a day, 365 days a year, eliminating the need to manually enter data, analyze, and create documents for daily reports.
Because it is a wireless system, it reduces the hassle of wiring work when changing the layout of equipment, updating, or expanding.
