Pump Automation Controller—Apply the SEL-2411P to provide a ready-to-use automated controller for pump applications, including closed-loop control for pump up/down using local or remote level sensors or single- or multifloat switches. Other features include alternator control, configured alarms, and configurable failover control for loss of level sensing and loss of communications. The SEL-2411P provides an interface for local setup and control when a SCADA interface is not available. The controller comes with a configured DNP3 map for scalable SCADA applications and includes the Modbus protocol as well as Ethernet and serial interfaces. This featured application is coming soon.
Trip Coil Monitoring—Assess the heath of a circuit breaker by capturing trip coil performance in real time. Record trip coil dynamics, including current, voltage, and temperature during operations, to plan preventative maintenance.
Station Control—Control plant variables and processes locally or remotely with powerful logic, flexible I/O, and deterministic communications.
Automatic Transfer Scheme—Sense voltage loss on the normal source and transfer the load to a standby source with Mirrored Bits communications over metallic or fiber-optic cable.
Local Control and System Applications—Send analog and digital input data to a central communications system, and receive and execute control commands. Deploy SELect I/O options suitable for your application needs, including digital or analog outputs, RTD, ac currents, and ac voltage inputs.
Isolation for Adverse Conditions—Protect equipment with fast analog alarms that execute every quarter cycle to detect overvoltage and undervoltage.
Transformer Monitoring and System Control—Detect transformer alarms, and monitor and control fan operation based on temperature. Send warnings to remote monitoring systems, and take protective action.
Time-Critical Applications—Optimize applications using time-deterministic, high-speed processing. Use control equations with logic, arithmetic, analog comparison, edge-trigger, and timer functions for automatic local control and to convert individual data values into actionable system information.
Flexible I/O for Local Control and System Applications
The base unit includes three digital outputs and two digital inputs. There are four card slots for optional SELect I/O cards, including the following:
Convenient Customizable Controls
Four programmable pushbuttons are provided on the front panel. Print labels for six front-panel LEDs to show channel activity, device status, critical I/O status, or the results of logic calculations. Label four pushbuttons and associated LEDs to simplify operator interaction.
Communications and Integration
EIA-232 ports are standard features while an 10/100BASE-T Ethernet port, fiber serial port, and EIA-232/EIA-485 serial port are optional. Standard Ethernet protocols include Telnet, FTP, and Modbus TCP, and optional protocols include DNP3 LAN/WAN and IEC 61850. Standard serial protocols include SEL ASCII, Compressed ASCII, SEL Mirrored Bits communications, and Modbus RTU, and optional protocols include DNP3 Level 2.
Local Control With SELogic Control Equations
Easily program with powerful math and logic. Use control equations with logic, arithmetic, analog comparison, edge-trigger, and timer functions for automatic local control and to combine data into system information. Time-deterministic, high-speed processing is ideal for time-critical applications.
High Reliability and Rugged Design
Apply in harsh substation environments; the SEL-2411 withstands vibration, electrical surges, fast transients, and extreme temperatures. Compare our superior specification compliance, higher reliability, lower cost, and ten-year, worldwide warranty. For even harsher environments, order conformal coating for the printed circuit boards to provide an additional barrier to harsh environments and airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture.
