Axion Modules

The SEL-2241 is a dedicated 4-port RTAC module for the Axion. Use it to integrate I/O, substation IEDs, SCADA communications, and security applications all in one device.

• Integrated web-based HMI with acSELerator Diagram Builder
• Copper or fiber Ethernet ports
• IEC 61850 GOOSE messages
• Optional conformal-coated circuit boards

The SEL-2243 Power Coupler is the Axion system power supply. Use a single power coupler in each node when reliable service power is available. For even higher system availability, use redundant power couplers in each node when dual service feeds are available. Additionally, the SEL-2243 provides two dedicated EtherCAT ports to accomodate the integration of multiple nodes.

• Copper or fiber ports for EtherCAT networking
• Optional conformal-coated circuit boards

The SEL-2245-22 DC Analog Input Extended-Range Module includes 4 inputs for measuring 0–300 Vdc signals. This makes them ideal for monitoring battery voltage or trip coil currents.

Budgetary Pricing: $840

The SEL-2245-3 DC Analog Output Module includes eight software-selectable current or voltage outputs. The outputs are self-sourcing from –20 to +20 mA or –10 to +10 V. This module supports a ramp feature for smooth transitions between setpoints and supports a clamp feature to prevent driving beyond a desired value. A total of three [SEL-2245-3] Modules can be installed in one SEL-2242 chassis and up to sixteen modules in one Axion System. This module is ideal for proportional-integral-derivative (PID) output controls, analog meter displays, and analog setpoint delivery.

The SEL-2245-4 AC Metering Module includes four current transformer (CT) and four potential transformer (PT) inputs with ranges of 0–22 A and 5–400 V L-N at a typical accuracy of 0.1 percent. Up to 9 modules may be used in a node and a maximum of 16 metering modules may be used in one Axion system, all with synchronized measurements for a common reference. Additionally, the module records waveform oscillography up to 24 kHz and generates IEEE C37.118 synchrophasors.

Budgetary Pricing: $1,082

The SEL-2245-42 Module includes three current transformers with isolated returns and includes three potential (or voltage) transformers for measuring ac signals. This module has galvanically isolated inputs and can sample events at user software-selectable rates of 1, 2, 4, 8, and 24 kHz. Up to 16 AC Protection Modules can be used in one Axion system and feature synchronized measurements throughout all modules. This enables time-deterministic control algorithms to take advantage of the common reference for all measurements, even those in distributed locations. Collect IEEE C37.118.1a-2014–compliant synchrophasor data from up to 64 phasor quantities. Provide digital fault recording (DFR) capabilities with the Axion to record and analyze power system dynamics and validate equipment performance.
