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.
Alarm Identification—Apply configurable labels to uniquely identify each alarm point LED. Preprinted labels (with factory default text), blank label media, and a Microsoft Word template on CD-ROM are included.
Monitoring and Control—Test and commission annunciator panels with live device status information on an acSELerator QuickSet SEL-5030 Software human-machine interface (HMI) screen. Operate and monitor the device remotely from a virtual front panel.
Custom Configuration—Create as few or as many points as needed for each application by using programmable logic. Implement multiple alarm panels for high-density alarm applications. Indicate the status of up to ten alarm points.
Digital I/O Sequential Events Recorder (SER)—Assign different element names to each defined SER point for the asserted and deasserted states. Provide a clear view of an event to operators and viewers.
Contact Follower—Provide a digital output corresponding to each digital input. Repeat the state of the input, and allow connection to a programmable logic controller (PLC), remote terminal unit (RTU), interlocking device, or other intelligent electronic device (IED).
Individually labeled columns and rows for easy identification
Field-configurable alarm window labels
Silence, acknowledge, reset, and test pushbuttons
Front EIA-232 port for easy access to settings and status
Two standard EIA-232 ports for DNP3 and SEL protocols
IRIG-B input to tag events to 1 millisecond
Optional communications card with EIA-232 or EIA-485 port
Communicate with up to four high-speed serial ports via DNP3, Modbus, or SEL protocols. Three EIA-232 ports are standard; one EIA-485 or EIA-232 port is optional.
Connect a precise time source, and time-tag alarm events to the nearest millisecond. Report time-tagged messages with DNP3 or the SEL Fast SER protocol.
Select from six International Society of Automation (ISA-18.1) standard sequences. Implement other ISA sequences with new custom sequence settings. Superbright LEDs provide an easily visible alarm indication in any lighting condition. Red or amber bicolor LEDs add flexibility.
Create custom alarm conditions using programmable logic to combine inputs and communications data without costly wiring.
Meet the demands of your harshest environments. The SEL-2533 exceeds stringent vibration, electrostatic discharge, electromagnetic interference, and temperature requirements.
Print custom alarm labels using the terminology that matches your application. Easily reprint labels to accommodate expansion, reconfiguration, or other changes.
