Connection diagram
The NRG bus chain can be connected to the ethernet network via the pair of RJ45 connectors located on the NRG
controller. The NRG can be configured in any network topology. If more than 32 solid state relays are required in an
application, multiple bus chains can be utilised. These can be configured in a line or star topology as deemed fit for
the application. The most favourable topologies for an EtherCAT network are line and ring. Wiring between EtherCAT
devices should follow the standard EtherCAT cabling guidelines (max. 100m).
