Abstract: An Acquisition, Control and Measurement device has the capability to operate as element in an Electrical Distribution of Average Tension Network or in an Electrical Substation, operating as master device (initiates the communication) or slave (responds the communication) in SCADA (Supervisory Control and Data Acquisition) systems. The device can process logical states and analogical signals, and has the capability to handle digital outputs using relay contacts and optoisolated digital inputs. The device can be used to simultaneously interconnect control equipment into diverse systems of acquisition through communication ports and standard communication protocols. Remote devices can access a data base using any means available. The device can be used as a data concentrator and/or protocol translator and includes a virtual connection of the transparent port type for communication towards other devices that manage software without data conversion through the communication ports.
