Ronan Systems X118 Serial Input Visual Annunciator PLC Processors in Chico, TX, USA

The Ronan Systems Model X118 Serial Input Visual Annunciator provides for a more economical and advanced technical approach than a conventional, split architecture annunciator system. Plant distributed process contacts are multiplexed and the status information transferred via serial link to the X118 controllers. This approach eliminates long runs of multi-conductor cables from the field contacts to the annunciator logic and displays.
A typical serial input annunciator consists of a conventional window or graphic display and a number of integral or remote mounted X118 controllers. Each controller services up to 48 windows, indicators, or repeater relays. For larger applications, additional controllers are daisy-chain connected to receive the serial data from a standard ASCII port of a Sequence of Events Recorder (SER), Programmable Controller (PLC), Distributed Control System (DCS), Plant Computer, or X120 Field Multiplexers.
