- 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.
