rack-mount alarm annunciator
Options and accessories:
This compact, ten-window annunciator is ideal for displaying alarm conditions and notifying personnel of abnormal conditions in each individual rack, panel, generator, equipment block, power line terminal, assembly line, conveyor, or other apparatus. Communications ports on the annunciator enable many cost- and labor-saving configurations. For example, use the SEL-2533 Annunciator as a combined annunciator and field I/O module by wiring contact inputs and outputs to the SEL-2533 and then communicating digitally to a plant's distributed control system (DCS), SEL Real Time Automation Controller (RTAC), another SEL-2533 station computer, or other device. Or, order the SEL-2533 without any local I/O, and drive the annunciator inputs with information from remote devices via the communications ports.
