RG..D..N RG..D..N RG 1-phase solid state relays with a communications interface Communication interface for real time monitoring only Benefits Communications interface. Solid state relay parameters and diagnostic data are accessible in real time. Reduced maintenance costs and downtime. Use of real-time data for prevention of machine stoppages during operation. Good quality products and low scrap rates. Real-time monitoring allows timely decisions for better machine and process management. Reduced efforts in troubleshooting. Distinguished faults to facilitate and reduce troubleshooting time. Versatile. Easy integration in existing machines as the control of the solid state relay does not change compared to a solid state relay without a communication interface. Fast installation and set-up. The solid state relays on RGS..D..N the BUS are addressed by Auto- addressing for fast set- RGC..D..N up and prevention of incorrect settings. Compact dimensions. Slimline RG series for a minimum product width of 17.8 mm, 1x DIN, up to 37 AAC at 40C. Description The RG..N solid state relays are the switching components in the NRG BUS chain. Switching of the RG..D..N is controlled by a voltage in the range of 4-32 VDC applied to the specific RG..D..N. In addition to the typical switching function of a solid state relay, the RG..N has integrated monitoring and a communication interface to provide data of the monitored variables and diagnostic information in real-time. The variables that can be read out from each RG..D..N are current, voltage, frequency, power, energy consumption and running hours. The status of each RG..N is accessible and in case of an unhealthy status, the specific fault is indicated to facilitate troubleshooting. The RG..N cannot interface directly with the system controller (PLC) but needs to be addressed in an NRG BUS chain (as explained further on). 1 NRG BUS chain can handle up to 48 RG..D..Ns. The first RG..N in the BUS chain is connected to the NRG controller, whilst the last RG..N in the BUS chain has to be terminated with a BUS terminator provided with the NRG controller. The RGC..N has an integrated heatsink and output ratings go up to 660 VAC, 65 A. The RGS..N does not have an integrated heatsink. Maximum output ratings of the RGS..N go up to 660 VAC, 90 A. LEDs on the front facade give a visual indication of the status of the RG..N output, any ongoing communication and the alarm status of the RG..N and its respective load. Specifications are noted at 25C unless otherwise specified. Applications 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 machinery, sterilisation machinery, drying tunnels and semiconductor manufacturing equipment.

Each NRG BUS chain consists of the following 3 components: the NRG controller the NRG solid state relay(s) the NRG internal BUS cables The NRG controller is the interface to the machine controller. It acts as the master of the BUS chain when performing specific actions on the respective BUS chain, and acts as a gateway for the communication between the PLC and the RG..N solid state relays. It is not possible to operate the NRG system without the NRG controller. The NRG controllers available are: NRGC The NRGC is an NRG controller with a Modbus RTU interface over RS485. The NRGC is addressed via the assigned Modbus ID (from 1-247). In an NRG system operating on Modbus it is possible to have 247 NRG BUS chains. The NRG solid state relay is the switching component in the NRG system. Each RG..N integrates a communication interface to exchange data with the machine controller (or PLC). The available RG..Ns that can be used in an NRG system are: RG..D..N The RG..D..N are solid state relays for use in an NRG system having the communication interface only for real time monitoring. Control of the RG..N is done via a DC control voltage. It is possible to have maximum 48 RG..D..Ns in one NRG BUS chain. RG..CM..N The RG..CM..N are solid state relays for use in an NRG system having the communication interface for control of the RG..N through the BUS and for real time monitoring. It is possible to have maximum 32 RG..CM..Ns in one NRG BUS chain. It is not possible to mix RG..D..N and RG..CM..N in the same BUS chain. The NRG internal BUS cables are proprietary cables that connect the NRG controller to the first RG..N in the NRG BUS chain and respective RG..Ns on the BUS. The internal BUS terminator, provided in the same package with the NRG controller, shall be plugged to the last RG..N in the NRG BUS chain. 11/06/2020 RG..D..N DS ENG Carlo Gavazzi Ltd. 2
