Connection Diagrams
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. Wiring between EtherNet/IP devices should follow the standard EtherNet/IP cabling guidelines.

The NRG Controller supports the Device Level Ring (DLR) protocol and therefore can also be configured in a ring
topology.
