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.

RSGD 45 MM: SELF-LEARNING SOFT STARTERS WITH MODBUS COMMUNICATION FOR AC INDUCTION MOTORS

Very compact soft starter with minimal settings, self-learning algorithm and real-time monitoring.

Lainate, July 2022 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, today presents the RSGD 45mm soft starters with Modbus communication.

The RSGD soft-starters are equipped with a Modbus/RTU communication port via a 2-wire RS485 connection, allowing the user to have a complete and easy real time monitoring of the product. In that way variables for energy consumption, voltage, current and other electrical variables can be easily communicated to a PLC for real-time monitoring of the motor condition.

The integration of a Class 10 electronic overload provides an advanced motor protection and results in further space saving on the electrical panel. Phase sequence protection and overload function can be enabled and disabled easily through the frontal push button.

The RSGD is the easiest to use soft-starter for 3-phase AC motors, as only 3 setting are required (FLC, ramp-up, ramp-down). The self-learning algorithm adjusts the soft starters parameters to work with different applications and varying load conditions without the need of adjusting the initial torque setting.

“As a means to allow our customers to have a real-time condition monitoring of the product, we have selected Modbus as our main communication interface on the RSGD. This serial communication protocol enables detection of any deviations in performance providing sufficient historical data that facilitates troubleshooting activity in the case of faults,” Brian Gauci International Product Specialis states. “High efficiency motors require high levels of starting current, causing more disturbances to the electrical network. Our RSGD soft starters are an advanced solution to counteract this issue.”

Developed in our competence centre in Malta, the RSGD soft starters will significantly enhance our offering to various sales channels and will thus make our offering more appealing to distributors and potential PLB partners. Typical applications are pumps, fans and compressors in Water and waste water, Agriculture, Energy and building efficiency, and HVAC markets.

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
