Introduction
1.1
Foreword
The NRG described hereafter is a sub-system made up of a number of solid state relays intended for the switching
of heaters in a machine. The solid state relays in this system are able to communicate with the main controller
through an NRG controller that facilitates communication between the solid state relays and the main controller.
The NRG controller is available for various communication interfaces including PROFINET. EtherNet/IP and Modbus
RTU. Through this communication, it is possible for the main controller to control each solid state relay, read
measurements related to each specific solid state relay and to identify specific failure modes related to the solid
state relay or its associated heater load.
