Intelligent RTU: An Industry Smart Data Acquisition

Abstract

It is a SCADA unit of remote terminal system which can be used to interface with any kind of data acquisition systems at distant places due to its modular architecture. The added feature is that the Input output channel of the RTU is expandable. Ideally any number of data acquisition cards can be connected at a time and be made to interact with the system. CPU automatically identifies the type of I/O card inserted. It can be connected to SCADA, which controls several units in industries. All I/O channels are isolated and protected against ESD, EFT and voltage surges. System is equipped with communication interfaces like RS485, RS232, USB, GPRS, and Ethernet. Memory unit includes SD card.
