SEL-2240

Axion

NEW—AXION BAY CONTROLLER WITH 7-INCH COLOR TOUCHSCREEN

The SEL-2240 Axion is a fully integrated, modular input/output (I/O) and control solution for utility and industrial applications, including use as a remote terminal unit (RTU) or ultrarugged programmable logic controller (PLC). With an optional 7-inch color touchscreen display, the Axion is also ideal for application as a bay control unit.

The Axion 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.

All of the Axion modules are rated from –40° to +85°C (–40° to +185°F) 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 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.

NEW Bay Controller—Combine the scalable architecture of the Axion with a fully integrated, 7-inch touchscreen display and the powerful logic engine of the RTAC for a comprehensive bay control and monitoring solution. The Axion's modular configuration allows you to expand the device to control and monitor over a hundred switching devices in your substation bay. This flexible design scales to hundreds of digital and analog input and output points for a single panel. Control and monitor circuit breakers, disconnect switches, and earthing switches of multiple bays with a single Axion.

Digital Fault Recording (DFR) System—Use the SEL-3555 RTAC with Axion modules, including the SEL-2245-42 AC Protection Module, to develop DFR solutions that exceed the requirements of NERC PRC-002. The SEL-2245-42 Module features 24 kHz recording with recording group configuration for combining multiple module event reports, including digital values, into a single COMTRADE file. The SEL-3555 RTAC with SSD storage provides the perfect controller for recording applications to maintain more than the minimum ten-day storage requirement of all fault records, dynamic disturbance records, and Sequence of Events (SOE) records in the substation.

SCADA RTU—Enable substation reporting and control by using the included serial and Ethernet communications protocols along with 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.

Flexible Synchrophasor Measurement Unit—Apply the Axion as a scalable and distributable phasor measurement unit (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

Power Management Integration With Industrial Control System—Provide a powerful gateway between the substation and the factory using EtherNet/IP. This popular industrial protocol facilitates reliable communication between electronic devices in industrial automation systems. Use the RTAC EtherNet/IP adapter to exchange critical data for real-time monitoring, process control, and power system integration.

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 Simple Network Time Protocol (SNTP)/Network Time Protocol (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.

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

Industrial Control System and PID Control—Create an ultra-rugged 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.

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.
