Real-time data reduces costs & machine downtime
20 March 2019
Designed to meet the needs of machine builders as well as Industry 4.0, Carlo Gavazzi has launched its NRG series of solid-state relays.
The NRG platform has been developed to fit the purpose of industry 4.0, which optimises manufacturing operations quickly and efficiently by providing information such as maintenance, performance and other issues that may need attention. The NRG series consists of one or up to 247 BUS chains providing real-time data monitoring, prevention of machine breakdown and accurate troubleshooting.
The communication interface in the NRG system allows read out of variables such as voltage, current, frequency, energy consumption, power and running hours of the solid state relays RG..N in real time. Diagnostic data such as mains loss, load loss, SSR short circuit, over temperature, SSR out of (set) limits are accessible through Modbus RTU over an RS485 interface. In addition to the above alarms the NRG controller has a configurable NO/NC auxiliary output.
The NRG system is extremely flexible and allows the user to modify default limits to adapt to their own specific needs. The solid state relays space saving design in the NRG series are available either with heatsink (RGC..N) or without heatsink (RGS..N) for ratings up to 660 V, 65 AAC and 90 AAC respectively. Significant time savings are achieved since there is no need to physically set the ID of each individual RG..N in the system. Through an Autoconfiguration command each RG..N is assigned a unique ID, based on its physical location on the BUS and the NRGC ID to which it is connected preventing any incorrect settings.
The NRG series suits any heating application where reliable and precise maintenance of temperatures is crucial to the quality of the end product. Typical applications include plastic machinery such as injection machines, extrusion machines and PET blow moulding machines, packaging/wrapping machinery, sterilisation machinery, drying tunnels and semiconductor manufacturing equipment and are CE, UL, VDE, EAC and CCC certified.
