Products

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

Compact, precision-time device for limited space and high-accuracy timing to ±100 nanoseconds.

The SEL-2407 provides time display, reliability, durability and high-accuracy timing to ± 100 nanoseconds.

The SEL-2411 offers rugged I/O for SCADA, PLC, monitoring, and control in harsh physical and electrical environments.

The SEL-2411P Pump Automation Controller is a complete preconfigured, SCADA-ready system for control and monitoring of water and wastewater pump applications.

The SEL-2414 Transformer Monitor provides an exceptional combination of monitoring, control, and communications in a compact package.

The SEL-2431 is compatible with most 32-step, single-phase voltage regulators manufactured in North America. Use various hinge and wiring kits to easily upgrade existing controls without removing the regulator from service. Quickly integrate the SEL-2431 into existing communications schemes using EIA-232, EIA-485, fiber-optic ST, or fiber-optic V-pin connectors.

The SEL-2440 DPAC is a 48-point discrete programmable automation controller that is ideal for utility and industrial applications as a rugged and reliable I/O solution at an economical price.

The SEL-2488 raises the bar for satellite-synchronized clocks by providing industry-leading accuracy, time distribution, security, and ease of use not offered in other critical infrastructure clocks.

The SEL-2730M is a managed 24-port Layer 2 switch. Apply the switch to build reliable, safe Ethernet networks in electrical substations, plants, and other mission-critical sites. Connect to devices using shielded Category 5/5e/6 copper cables and single- or multimode LC fiber-optic cables.

The SEL-2730U is an unmanaged 24-port Ethernet switch, designed for the harsh environments commonly found in the energy and utility industries. The switch supports communications infrastructure built for engineering access, supervisory control and data acquisition (SCADA), and real-time data communications, while offering the same reliability found in SEL protective relays.

Communicate up to 4 kilometers on multidrop and point-to-point EIA-485 networks

Carry an SEL-2924 for an always-secure wireless EIA-232 connection.

The SEL-3573 Station PDC is a hardware-based phasor data concentrator with integrated archiving. It concentrates as many as 120 phasor measurement unit (PMU) inputs at rates as fast as 240 messages per second, exceeding the IEEE C37.118-2011 requirement of 60 messages per second. Additionally, the SEL-3573 includes a built-in archiving feature that can be used as part of a NERC PRC-002-2 disturbance recording system. Local archiving of data at each substation protects against loss of data, even in the event of a communications outage. The SEL-3573 offers archiving for both continuous and predefined trigger conditions, so it never misses capturing data necessary for post-disturbance analysis. The SEL-3573 provides the real-time performance needed for synchrophasor-based control schemes.

The SEL-9524 GNSS antenna for critical infrastructure applications is capable of receiving signals from both GPS and GLONASS satellite constellations. It is manufactured to be robust and reliable.

The SEL-9929 Kit is a ready-assembled kit consisting of the SEL-2401 Satellite-Synchronized Clock, the SEL-3401 Digital Clock Display, and all necessary accessories.
