Do More With the SEL-2240 Axion RTAC

Five times the processing power. Thirty-three percent more digital inputs.

A Comprehensive Control and Monitoring Solution

The upgraded Axion SEL-2241-2 Real-Time Automation Controller (RTAC) module is powered by the same CPU as our popular SEL-3350 RTAC, while the new 32 digital input module delivers more input density than any other Axion module. And with its hardened design, the upgraded Axion is a comprehensive control and monitoring solution engineered to operate reliably for decades, with little or no human intervention.

Upgrade Your RTU

With its modular design and dense I/O options, the Axion is the exact device you need for your new or retrofit projects. Featuring enhanced processing power, the upgraded Axion is an all-in-one remote terminal unit (RTU) data concentrator and substation gateway that supports hundreds of digital input connections. With both analog and digital inputs and a variety of protocols, including IEC 61850, the Axion brings high performance and deterministic control to your installation.

Control Substation Bays

The new high-performance RTAC module powers a 7-inch touchscreen for use as a local HMI for bay control applications. Custom bay screen designs and programmable alarms make it easier to control and monitor breakers, switches, instrument transformers, and other equipment. Its expandable design and new module options address the complexity of new bay controller installations as well as retrofits.

Deploy an Advanced DFR Solution

For a comprehensive digital fault recorder (DFR) solution, pair the Axion with an SEL-3350 RTAC for continuous data recording or use the Axion with an upgraded SEL-2241-2 RTAC module to stream measurements to any IEEE C37.118-compliant historian. With more than 96 analog channels, the Axion supports continuous waveform streaming at 3 kilosamples per second (ksps) and captures event reports at 24 ksps with 24-bit resolution and submicrosecond accuracy.

Capture Every Disturbance

As the power system incorporates more distributed energy resources and nonlinear loads, disturbances may become too unpredictable to be identified by traditional monitoring devices. Deploy the Axion to capture these disturbances by using continuous waveform streaming, which provides gapless 3 ksps recording of voltage, current, and energy packets.
