The Allen-Bradley DataSite remote terminal unit (RTU) controller from Rockwell Automation is a PLC that processes a user program, and controls and monitors the operation of other equipment, in remote locations with extreme temperatures, such as those in the oil and gas, and wastewater industries. It features an advanced 32-bit processor with an embedded real-time, multitask operating system, as well as serial and Ethernet ports. In addition, it has a HART multi-drop port that can monitor up to 13 instruments on a two-wire system. It is available in an electronic flow meter version (EFM) tailored for natural gas wellhead monitoring and offers firmware specially designed to calculate natural gas flow.
