April 2026, Electrical Power & Protection, Editor's Choice, Beckhoff Automation

With a seamless modular control solution from Beckhoff featuring over 500 data points and numerous ELX series terminals with intrinsically safe interfaces, Greenlight Innovation is breaking new ground in hydrogen testing.

Edge I/O NTS and the need for industrial speed
April 2026, IT in Manufacturing, Schneider Electric South Africa

One of the most compelling solutions to emerge from industrial automation is Edge I/O NTS, which represents a natural evolution of computing from centralised servers to localised, device-level input/output processing, offering improved speed, efficiency and resilience.

How batteries can help SA avoid a grid crisis
April 2026, Electrical Power & Protection, WEG Africa

Last year, Spain and Portugal lost up to 60% of their electrical power in mere seconds. It’s crucial that SA avoids a similar grid crisis, and battery energy storage systems are vital for that transition.

Vector network analyser with high dynamic range and precision
April 2026, Electrical Power & Protection, Vepac Electronics

The SNA6000A vector network analyser from Vepac Electronics has a dynamic range of over 135 dB, which makes it ideal for the detailed analysis of weak signals, even when they occur alongside stronger signals.

Why it pays to outsource boiler operations
April 2026, Electrical Power & Protection

Associated Energy Services has improved energy efficiency by 35% at a large FMCG manufacturer’s site and followed up with a 21% improvement at a second.

Open automation is breaking legacy chains
April 2026, IT in Manufacturing, Schneider Electric South Africa

Industrial automation is now entering a new era defined by open, software-driven principles that are breaking decades of hardware-bound limitations.

Sustainable manufacturing
April 2026, IT in Manufacturing, ABB South Africa
