## **NRG** 

## **The solid state relay solution with real-time monitoring through Modbus** 

## **Benefits** 

- **Fieldbus interface.** Solid state relay parameters and diagnostic data are accessible through Modbus RTU over an RS485 interface. 

- **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 processes management. 

- **Reduced efforts in troubleshooting.** A number of faults can be distinguished to facilitiate 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. 

## **Description** 

The **NRG** is a system consisting of one or more BUS chains that communicate with the main controller in the machine through Modbus RTU over an RS485 interface. 

- **Fast installation and set-up.** The solid state relays on the BUS are configured by AutoConfiguration for fast setup and prevention of incorrect settings. 

- **Compact dimensions.** Adopts the same compact platform of the slimline RG series with a minimum product width of 17.8mm, 1x DIN, up to 37 AAC @ 40°C. 

The communication interface in the **NRG** system allows read out of variables such as voltage, current, frequency, energy consumption and power of the solid state relays **RG..N** in real time. The status of the components in the NRG system is readable with an identification of the specific fault to faciliate troubleshooting. The **NRG** system is very flexible and allows the user to modify default limits to adapt to the own specific needs. 

The **RG..N** solid state relays in the NRG are suitable for switching of heater loads and their switching is controlled by a DC voltage in the range of 4-32 VDC. In case of a malfunction of the communication interface, the **RG..N** switching function is not affected. The switching function is solely dictated by the presence of the control voltage. 

## **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 

- Modbus RS485 interface for real-time monitoring

## **Description** 

The **NRG** system may consist from 1 up to a maximum of 247 BUS chains. Each BUS chain consists of 1 NRG controller, the **NRGC** and a maximum of 48 **RG..N** solid state relays.  The main controller in the machine uses Modbus RTU to communicate with the respective BUS chains. Each NRGC in the system needs to be assigned a Modbus ID and hence the limitation of 247 NRGCs in the system. 

The **NRGC** acts as a master of the respective BUS chain when it is requested by the main controller to carry out specific actions on the BUS chain, for example when an AutoConfiguration needs to be exectuted to automaticaly assign a valid ID to each RG..N on the BUS. Otherwise, the NRGC is just a facilitator of the communication between the main controller and each individual RG..N solid state relay in the system. 

The **RG..N** solid state relays are physically linked to the NRGC through an internal BUS using proprietary cables **RCRGN-xxx-2** available at various lengths.  Each RG..N in the NRG system needs to be uniquely identified for the main controller to be able to access its data. Great 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.

## **Description** 

The **RG..N** solid state relays are the switching components in the NRG BUS chain. Apart from the switching function, they have integrated monitoring components and a communication interface to provide data of the monitored variables in real-time. 1 BUS chain can handle up to 48 **RG..Ns** . 

The first **RG..N** in the BUS chain is connected to the **NRG** controller, **NRGC** , whilst the last RG..N in the BUS chain has to be terminated with a BUS terminator provided in the packaging of the **NRGC** . 

The **RG..Ns** solid state relays are available either with integrated heatsink, **RGC..N** or else without heatsink, **RGS..N** . Output ratings go up to 660 VAC, 65 AAC for the **RGC..N** and 90 AAC for the **RGS..N** . Switching of the **RG..N** is controlled by a DC voltage in the range of 4-32 VDC applied through a spring pluggable terminal. 

A voltage reference connection is required to enable measurement of voltage and other variables using the voltage measurement. LEDs on the front facade give a visual indication of the status of the solid state relay output, any ongoing communication and the alarm status of the solid state relay and its respective load. 

Specifications are noted at 25°C unless otherwise specified.

## Note: 

- Control input lines must be installed together to maintain products’ susceptability to Radio Frequency interference. 

- Use of AC solid state relays may, according to the application and the load current, cause conducted radio interferences. Use of mains filters may be necessary for cases where the user must meet E.M.C requirements. The capacitor values given inside the filtering specification tables should be taken only as indications, the filter attenuation will depend on the final application. 

- Performance Criteria 1 (PC1) : No degradation of performance or loss of function is allowed when the product is operated as intended. 

- Performance Criteria 2 (PC2): During the test, degradation of performance or partial loss of function is allowed. However when the test is complete the product should return operating as intended by itself. 

- Performance Criteria 3 (PC3): Temporary loss of function is allowed, provided the function can be restored by manual operation of the controls.

## **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.

## **NRGC** 

## **NRG controller with Modbus RTU over RS485** 

## **Main features** 

- Communication interface: Modbus over RS485 

- Connects up to 48 RG..N solid state relays 

- Supply voltage: 24 VDC +/- 20% 

- 1 configurable electromechnical relay output (default set as Alarm output) 

- Product width: 35mm 

- Selector switch for Modbus addresses 1-15 * 

- LED indication for ON, COM, BUS and ALARM status 

- (Modbus addresses 1 - 247 through comms) 

## **Description** 

The **NRGC** is the controller of the NRG BUS chains and interfaces directly with the main controller of the system through Modbus RTU on an RS485 interface. Each NRGC in the system is identified by a unique Modbus address that can be set  either manually via a front selector switch that allows only Modbus addresses 1 to 15 or through dedicated registers for addresses 1 to 247. The default Modbus communication settings can also be modified via dedicated registers. 

The NRGC acts as a master of the respective BUS chain when it is requested by the main controller to carry out actions on the specific BUS chain. Otherwise, the NRGC is just a facilitator of the communication between the main controller and each individiual RG..N solid state relay in the system. 

The NRGC needs to be supplied with 24 VDC. It is equipped with a digital output consisting of an electromechanical relay that is set as an NRGC alarm relay as the default setting. This can be modified and set as an auxiliary digital output to be controlled by the main controller of the system. 

LEDs on the front facade give a visual indication of the status of the NRGC, of any ongoing communication with the main controller (COM) and the RG..Ns on the BUS chain (BUS) and of any alarm condition of the NRGC. 

Specifications are noted at 25°C unless otherwise specified.

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

- Cables terminated at both ends with a microUSB plug 

- Connects the NRGC to the RG..N solid state relay and respective RG..N solid state relays 

## **Description** ~~>~~ 

The **RCRGN** cables are proprietary cables that must be used with the NRG system for the internal BUS. These cables connect the NRGC controllers to the RG..N solid state relays and respective RG..N solid state relays. 

The RCRGN... are 5-way cables carrying the communication, supply and autocofiguration lines. By means of autoconfiguration, the RG..Ns are assigned a unique ID based on the physical location and hence internal BUS wiring sequence when an autoconfiguration command is sent to the RG..Ns.
