The RCRGN-350-2 is a proprietary internal BUS cable designed specifically for the Carlo Gavazzi NRG system. This 5-way cable measures 350cm in length and is terminated at both ends with a micro-USB connector. It is engineered to carry communication, power supply (+24V, GND), and autoconfiguration lines between system components. The cable provides the essential physical link between an NRGC controller and RG..N solid state relays, or between multiple RG..N relays, enabling real-time monitoring and control in industrial automation.
