Selecting an appropriate Remote Terminal Unit (RTU) and sensors for an automation project can be daunting. There are numerous devices available with varied capabilities and performance. Factory representatives and specifications can be misleading and confusing. Advances in the electronics industry are seeing tremendous changes and subsequently RTUs and sensors are undergoing new developments. Older models are being redesigned and in some cases losing their integrity. Efforts have been made to test various RTUs and sensors, but they have not been exhaustive and these devices will eventually become obsolete. Considering the extensive choices that are available and the changes that are continually occurring, a criteria was developed for selecting these devices for automation projects. While basic performance criteria are important, it was concluded that consulting with individuals who have used these components is the most important.
