SEL-2533

Annunciator

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.

Communications
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.
Time-Tagged SER
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.
Comprehensive Annunciation
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.
Logic Processing
Create custom alarm conditions using programmable logic to combine inputs and communications data without costly wiring.
Reliability
Meet the demands of your harshest environments. The SEL-2533 exceeds stringent vibration, electrostatic discharge, electromagnetic interference, and temperature requirements.
Configurable Labels
Print custom alarm labels using the terminology that matches your application. Easily reprint labels to accommodate expansion, reconfiguration, or other changes.

• Contact Inputs and Outputs (I/O) There are three options for I/O on the SEL-2533:
  

  Description	Digital Inputs (DI)	Digital Outputs (DO)
  Remote Annunciator: Windows are driven by data from communications.	2	3
  Standard Annunciator: DI for each window.	14	7
  Annunciator With Follower Contacts: DI and DO for each window.	14	15

• Serial Ports
  The standard SEL-2533 Annunciator has one front-panel EIA-232 console port and one rear-panel EIA-232 port. A fiber-optic serial port and an additional EIA-232 or EIA-485 port are optional.
• Protocols
  The following protocols are included in the standard SEL-2533: SEL Fast Meter, SEL Fast SER, SEL Fast Operate, SEL Mirrored Bits communications, ASCII, and Modbus RTU. DNP3 Level 2 Outstation is optional.
• Conformal Coating
  Protect equipment from harsh environments and airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture.
