NRG solid state relays
The RG..N solid state relays are the switching components in the NRG system.
They are available with and without heatsink. For a reference of the variants
available refer to the RG..N datasheet. The RG..CM..N utilises the
communication system for switching, measurement and diagnostic thus
minimising the number of components required in the system.
Through the internal BUS, the main controller can read measurement
parameters and diagnostics information related to the RG..N and its load. The
RG..N is also capable of detecting certain fault conditions. A fault condition
is indicated through a red LED available on the façade of the RG..N. The type
of fault can be identified through a specific flash rate of the red LED and
identified via the communication system.
Since the main controller needs to address each specific RG..N individually, each RG..N needs to be uniquely
identifiable. It is not required to physically set the ID for each RG..N. This can be done through an auto-addressing
function which occurs automatically on the first start up; whereby each RG..N on the bus chain will automatically be
assigned an ID with respect to its physical placement on the internal bus.
NRG internal cables
The RCRGN-xxx-2 is a 5-way proprietary cable used for the internal BUS, i.e., between the NRG
controller and the first RG..N on the BUS chain and between respective RG..Ns on the BUS. This
internal BUS cable though terminated with a micro-USB plug is not a standard USB cable. Apart
from the data and supply lines, the RCRGN-xxx-2 are equipped with an additional wire utilised
for the auto-addressing of the RG..Ns on the NRG bus chain. These cables are available in
various lengths from Carlo Gavazzi.
