Programmable logic controller ( PLC ) Schweitzer Engineering Laboratories

Programmable Automation Controller - SEL-2411

Automatically control station auxiliaries, shed loads based on voltage or frequency, change configurations based on external conditions, and more. Powerful logic, flexible I/O, time-deterministic processing, and high reliability make the SEL-2411 an attractive alternative to a PLC. Include the ac current and voltage input modules, and use built-in oscillographic event reporting and three-phase power calculations. Use SELOGIC to set the trigger conditions. Base automatic control on real or reactive power limits, or send power data to a plant DCS or SCADA system. Sense up to 32 pressures, temperatures, fluid levels, or other process values with analog input cards. Report these values to SCADA or DCS systems, and use them in local automatic control equations. Store up to 512 Sequential Events Recorder (SER) reports of actual or calculated digital input transitions, time-tagged to the nearest millisecond. Send the SER data to a communications processor for system analysis and troubleshooting. Apply in harsh substation environments; the SEL-2411 withstands vibration, electrical surges, fast transients, and extreme temperatures. Compare our superior specification compliance and ten-year, world-wide warranty.
