Ronan X71 - Manual (Page 6)

The X71 graphic may include conventional
window annunciators mounted into the grid with
special mounting facilities. Due to the annunciators’
inherent heavy weight, there are limitations to their
size. For applications where large numbers of
windows are required, a combination of lamp cabinet,
incandescent or LED type, with remote annunciator
logic is recommended.
S E R I A L I N P U T A N N U N C I AT O R S
The most suitable approach for a larger number
of windows or indicators is to utilize the Ronan X110
Serial Input Annunciator Controller driven from a host
such as a PLC, Ronan X120 Field Multiplexer, or an
X500E Sequence of Events Recorder. Each X110
controller provides for 48 outputs with individually
selectable alarm sequence per output. The X110s are
typically mounted in the graphic enclosure or integral
to the rear of the graphic assembly.
