SEL-2240

Axion

The SEL-2240 Axion is a fully integrated, modular input/output (I/O) and control solution ideally suited for utility and industrial applications. It combines the communications, built-in security, and IEC 61131 logic engine of the SEL Real-Time Automation Controller (RTAC) family with a durable suite of I/O modules that provide high-speed, deterministic control performance over an EtherCAT network.

Whether your application calls for a remote terminal unit (RTU) or an ultrarugged programmable logic controller (PLC), the SEL-2240 will be a good match. All of the SEL Axion modules are rated from –40° to +85°C and can optionally include conformal coating. The system is designed to be flexible; use the right combination of modules and nodes in almost any arrangement to suit the job. The SEL-2244-3 Digital Output Module has substation duty contacts (30 A make, 6 A carry) in order to provide reliable operation and flexible application.

The SEL-3530, SEL-3530-4, SEL-3555 RTACs, and SEL-2241 RTAC Module can all operate as the CPU for an SEL Axion Platform. They interface seamlessly with the I/O modules and provide easy integration with other serial and Ethernet devices via preinstalled communications protocols. The RTACs also support multiple SCADA/HMI channels. For high-speed communication, use EtherCAT fieldbus connections to I/O modules or optional IEC 61850 GOOSE messaging with station IEDs.

SCADA Remote Terminal Unit (RTU)—Enable substation reporting and control by using the included serial and Ethernet communications protocols along with SEL-2240 Axion I/O Modules.

Synchronized CT/PT Measurements for Advanced Control—Employ synchronized CT/PT measurements from multiple Axion chassis distributed across a substation and from multiple Axion systems for advanced time-deterministic control applications, including load shedding and microgrid control.

System Security—Enable encryption for any engineering access channel or SCADA link. Implement system security auditing, logging, and password restrictions to enforce government standards. Utilize web upload features and project passwords. 

Flexible Synchrophasor Measurement Unit (PMU)—Apply the Axion as a scalable and distributable PMU. A single RTAC module in the primary Axion node serves IEEE C37.118.1a-2014 synchrophasor data from remote Axion PMU nodes. Remote Axion nodes use the SEL-2245-4 AC Metering Module located at the measurement points.

IEC 61850 GOOSE Concentrator—Gather a variety of substation I/O with the SEL-2244 Digital I/O Modules, and share the data with IEC 61850 GOOSE messages. Apply the protocol flexibility of the RTAC to concentrate data from non-IEC 61850 relays, and convert these data to GOOSE messages

Industrial Control System and PID Control—Create an ultra-rugged programmable logic controller (PLC) system by combining the standard IEC 61131 logic engine, integrated database, and flexible I/O. Use ladder logic, structured text, or function chart programming for custom control strategies. Support advanced process control strategies by implementing control function blocks, such as proportional integral derivative (PID).

Substation Battery Monitoring—Monitor substation battery levels and issue alarms using the new SEL-2245-22 DC Analog Input Extended-Range Module.

Automatic Trip Coil Monitoring—Assess the health of a circuit breaker by capturing trip coil performance in real time. Record trip coil dynamics, including current, voltage, and temperature during operations, and run automatic diagnostics to issue alerts for scheduling preventative maintenance.

SCADA Data Concentrator—Take advantage of multiprotocol support to collect SCADA information and process control commands, and obtain SNTP/NTP time synchronization through a single communications link to each Ethernet device

Remote I/O Expansion—Increase the number of I/O points with as many as 60 modules or six nodes connected to one resident SEL-2241 RTAC. Through EtherCAT connectivity, provide rapid data acquisition rates to the expanded I/O points within your automation system.

Event Recording—Record high-accuracy COMTRADE events with the Axion analog modules. Record up to 24 kHz event records with the SEL-2245-4 AC Metering Modules and up to 1 kHz event records from the SEL-2245-2 and SEL-2245-22 DC Analog Modules.

EtherCAT Network Topologies—The SEL-2243 Power Couplers provide not only hot-pluggable power supplies, but also fast EtherCAT connections to remote Axion nodes. The power couplers create EtherCAT links in a star network topology, sequential network topology, or combination of both. Apply single or dual power couplers in each Axion node based on connection or redundancy requirements.

Protocol Gateway—Collect downstream data with client protocols. Then, send these data to an upstream human-machine interface (HMI), RTU, or SCADA master with server protocols, converting the data from one protocol to another in the process.

How To Install and Setup SEL-2240 Axion

RTU and Programmable Automation Controller (PAC) in a Single System
The SEL Axion includes I/O, SCADA communications, and control logic support for many industrial and utility applications.

Synchronized Current and Voltage Measurements
The Axion CT/PT Module provides time-aligned current and voltage measurements for high-accuracy waveform recording and advanced power control algorithms.

Top-of-the-Second Synchronized Measurements
All measurements of the SEL-2245-4 AC Metering Module are synchronized to the top of the second to provide time-aligned data for wide-area control schemes with multiple Axion systems.

Modular Phasor Measurement Unit
Stream and process IEEE C37.118.1 compliant synchrophasor messages via the SEL-2245-4 AC Module, which has 4 CT and 4 PT inputs, as well as the SEL-2244-2 Digital Input Module, which has 24 digital inputs.

Simple Setup With acSELerator RTAC SEL-5033 Software
Build a system quickly, including I/O modules, using standard device templates.

Flexible I/O Selections
Choose a custom mix of digital I/O modules that suit the application. Include hundreds of points in a single panel, all connected to a deterministic EtherCAT network.

Advanced User Authentication and System Security
Enforce Lightweight Directory Access Protocol (LDAP) user accounts to maintain security perimeter integrity. Apply security corporate logging and port control policies to comply with NERC CIP requirements.

Deterministic I/O Performance
The connected I/O is updated at a deterministic frequency; all inputs provide 1 ms Sequential Events Recorder (SER) time stamps.
