A water utility monitors a pump station 40 km away over a cellular link. Which field device collects the local I/O and reports to the control center?
- A.An engineering laptop in the plant
- B.A safety relay inside the pump motor
- C.A remote terminal unit at the station
- D.A data historian at the control center
Why C is correct
An RTU is built for remote sites, gathers inputs and outputs locally and communicates telemetry over WAN links to the master station. A historian archives data, an engineering workstation programs devices and a safety relay does not report telemetry.
