NRG DIGITAL SOLID STATE RELAYS WHITE PAPER

Alleviating data challenges in Industrial Automation

The trend of Industry 4.0, automation in different manufacturing processes has triggered the implementation of Industrial IoT (IIoT) systems and the use of data-driven predictive modelling to improve the availability of production systems. The implementation of such advanced technologies brings about a number of challenges. This paper introduces the various challenges related to the data collection, its transmission and transformation and how the introduction of intelligent IIoT devices, such as the NRG digital solid state relays by Carlo Gavazzi, can alleviate such issues.

THE NEW NRG DIGITAL SOLID STATE RELAYS WITH A MODBUS TCP INTERFACE

Better interoperability with the additional ethernet-based protocols.

Lainate, May 2022 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, today presents an additional communication interface to the NRG family of digital solid state relays – the NRG with Modbus TCP communication.

The NRG range of digital solid state relays by Carlo Gavazzi is designed to face the digital transformation currently undergoing in industrial automation. Incorporating switching, monitoring, and diagnostics through a communication interface, the NRG enables real-time monitoring that is crucial to predict failures, reduce unplanned downtimes and optimize machine performance.

The NRG is currently available with PROFINET, EtherNet/IP™ and EtherCAT and today we are complementing the NRG range with a new controller with Modbus TCP. The availability of Modbus TCP in a wide variety of PLCs will broaden the interoperability of the NRG in the communication network of many industrial machines.

“Connectivity is the backbone of industrial IoT systems”, Dora Lee Borg International Product Specialist says. “The new NRG controller with Modbus TCP will enhance the adaptability of the NRG range of digital solid state relays to be implemented in a wider variety of applications”.

Developed in our competence centre in Malta, the NRG has been designed to suit any heating application where precise temperature control is crucial to guarantee the quality of the end-product and where unplanned machine stoppages can result in considerable loss of revenue. Typical applications are plastic injection machines, packaging machines, semiconductor manufacturing, drying machines, and glass tempering machines.

Main technical features
• Modbus TCP, EtherCAT (Conformance Tested), EtherNet/IP™ (ODVA conformant), PROFINET (PI certified) or Modbus RTU interface
• Up to 32 NRG solid state relays in 1 NRG bus chain
• NRG solid state relays ratings up to 660 VAC, 90 A
• Selectable switching modes: ON/OFF, Burst, Advanced Full Cycle, Distributed Full Cycle, Phase Angle and Soft Start
• Predictive failure detection with Load deviation indication
• Read-outs: Current, Voltage, Power, Energy consumption kWh, Load and SSR Running hours
• Malfunction detection: Mains loss, Load loss, SSR short circuit, SSR over-temperature, Voltage/Current/Frequency out-of-range

RVPM: VARIABLE FREQUENCY DRIVE FOR BRUSHLESS DC, PERMANENT MAGNET AND INDUCTION MOTOR COMPRESSORS

Fully targeted at heat pumps, chillers and commercial air-conditioning designed with variable speed compressors.

Lainate, March 2022 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacturing, and marketing of electronic equipment, today presents its new frequency drive for scroll compressors.

In the HVAC industry, eco-design directives have forced OEMs to improve the efficiency of heat pumps over the whole heating season. This means that heat pumps need to work efficiently at different operating points. The efficiency of heat pumps, known as seasonal coefficient of performance (SCOP) must be above certain limits or else the heat pump cannot be placed on the EU market. For this reason, variable speed compressors are becoming more popular in this market.

The RVPM fits this market’s requirements as it provides a compact and fully compliant product for use in heat pumps, both for the residential as well as commercial sectors.

The RVPM is a frequency drive that is specifically designed for scroll compressors typically used in heat pumps, industrial air conditioners, chillers and also commercial refrigeration cabinets. This device is designed with a sensor less vector control that can be used with BLDC, PMAC and IM motor types. It comes in two housings, one utilising what is known as the cold-plate and the other one with a heatsink. The cold-plate design enables significant space savings in heat pumps.

“The reduced set of parameters required to setup the RVPM facilitates its installation. OEMs can start running their compressor in a matter of minutes as minimal configuration is required. Furthermore the RVPM can control both BLDC and PMAC compressors as well as Induction motor compressors for an easier integration with a wider range of compressors.”, Jason Demicoli International Product Manager states. “With this new variable frequency drive, Carlo Gavazzi’s intention is to strengthen its growth in the HVAC&R market segment, providing customers with a more comprehensive range of products”.

Developed in our competence centre in Malta, the RVPM enables us to expand our presence in applications that are becoming more and more popular in HVAC systems such as heat pumps, chillers, commercial air-conditioning and commercial refrigeration cabinets.

Main technical features
• Operational voltage: RVPM 1-phase: 230 VAC , RVPM 3-phase: 400 VAC
• Power ratings: RVPM 1-phase: 4.5 kW, RVPM 3-phase: 8.0 kW
• Control method: Modbus RTU
• Compressor compatibility: BLDC, PMAC, IM compressor types
• Configuration software with compressor database for quick configuration and setup
• Built-in diagnostic functions: motor overload, over- and under-voltage, over-temperature and phase loss
• Smart functions: automatic speed and/or switching frequency reduction in case of operation at high temperature
• Crankcase heater function: replicates the functionality of the resistive heater that is used with scroll compressors
