Integrating SCADA with M&E Systems and Equipment

Applied Industrial Systems Ltd (AIS) is a specialist contractor, consultancy and system integrator providing design and build of PLC and SCADA based automation systems and their integration with plant equipment and services.

Our business focus is mainly on infrastructure – including critical national infrastructure – across airports, road & rail tunnels, ports and the built environment. We undertake both new build and refurbishment projects including safety rated systems – designing and delivering to BS EN 61508 and BS EN 50128 as required.


System integration is in our DNA. We specialise in making disparate systems work together as a single coherent system.
