- **Fast installation and set-up.** The solid state relays on the BUS are addressed by Auto- addressing for fast setup 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 40°C. 

## **Description** ~~Rm~~ 

## 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 (limited to 37 A for the RG..D..N variants)*. 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 25°C 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. 

## **Main function** 

- 1-phase AC zero cross solid state relays up to 660 VAC, 90 AAC 

- 4-32 VDC control for switching of the solid state relay 

- Communications interface for real-time monitoring

## **System overview** 

The NRG is a system consisting of one or more BUS chains that enable communication between the field devices (such as the solid state relays) and the control devices (such as the machine controller or PLC). 

Each NRG BUS chain consists of the following 3 components: 

1. the NRG controller (NRGC..) 

2. the NRG solid state relay(s) (RG..N) 

3. the NRG internal BUS cables (RCRGN-XXX-2) 

The NRG controller is the interface to the machine controller and determines the communication protocol used. It is not possible to operate the NRG system without the NRG controller. 

The NRG controllers available are: 

- **NRGC** - NRG controller with a Modbus RTU interface over RS485. 

- **NRGC-PN** - NRG controller with a PROFINET communication interface. The NRGC-PN is identified by a unique MAC address which is printed on the facade of the product. The GSD file can be downloaded from www. gavazziautomation.com 

- **NRGC-EIP** - NRG controller with an EtherNet/IP communication interface. The IP address is provided automatically via a BOOTP server. The EDS file can be downloaded from www.gavazziautomation.com 

- **NRGC-ECAT** - NRG controller with an EtherCAT communication interface. The ESI file can be downloaded from www.gavazziautomation.com 

- **NRGC-MBTCP** - NRG controller with a Modbus TCP communication interface. 

The NRG solid state relay is the switching and monitoring 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 max. 48 x RG..D..Ns in one NRG BUS chain.

## **RG..D..N** 

## **System overview - continued** 

- **RG..CM..N** 

The RG..CM..N are solid state relays for use in an NRG system having a communication interface for control of the RG..N through the BUS and for real-time monitoring. Different variants of the RG..CM..N can be mixed on the buschain with a maximum limit of 32 switched poles. The variants of the RG..CM..N are: 

- RGx1A..CM..N – 1-pole solid state relay with zero cross switching. 

- RGx1P..CM..N – 1-pole solid state relay with proportional switching. 

- RGC2P..CM..N – 2-pole solid state contactors with proportional switching. 

- RGC3P..CM..N – 3-pole solid state contactor with proportional switching. 

For a review of the features and compatibilities across all variants refer to the table below:

To be released soon.. 

## **Notes:** 

- **RG..D..N** and **RG..CM..N** devices cannot be mixed in the same bus chain. 

- The **NRG internal BUS cables** are proprietary cables to daisychain the RG..Ns on the NRG bus chain and to connect the NRG controller to the first RG..N. 

- The **internal BUS terminator** is provided in the same package with the NRG controller and shall be plugged into the last RG..N in the NRG bus chain.

## **Short circuit protection** 

## **Protection Co-ordination, Type 1 vs Type 2:** 

Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. In Type 2 co-ordination the device under test will still be functional after the short circuit. In both cases, however the short circuit has to be interrupted. The fuse between enclosure and supply shall not open. The door or cover of the enclosure shall not be blown open. There shall be no damage to conductors or terminals and the conductors shall not separate from terminals. there shall be no breakage or cracking of insulating bases to the extent that the integrity of the mounting of live parts is impaired. Discharge of parts or any risk of fire shall not occur. 

The product variants listed in the table hereunder are suitable for use on a circuit capable of delivering not more than 100,000A rms Symmetrical Amperes, 600 Volts maximum when protected by fuses. Tests at 100,000A were performed with Class J fuses, fast acting; please refer to the table below for maximum allowed ampere rating of the fuse. Use fuses only. 

Tests with Class J fuses are representative of Class CC fuses.

**NRG internal BUS cable** 

## **RG..D..N** 

## **RCRGN..** 

**Main features** • Cables available at various lengths for the internal BUS of the NRG system • Cables terminated at both ends with a microUSB plug • Connects the NRG controller to the RG..N solid state relay and respective RG..N solid state relays by . **Description** > The **RCRGN** cables are proprietary cables that must be used with the NRG system for the internal BUS. These cables are 5-way cables carrying the communication, supply and autoconfiguration / auto-addressing lines. By means of autoconfiguration / auto-addressing, the RG..Ns are assigned a unique ID based on the physical location and on the internal BUS. 

- Cables available at various lengths for the internal BUS of the NRG system
