The Bitronics Analog Output Converter(AOC) transmits the MultiComm and PowerPlex measurements to another device using analog signals. The AOC communicates with the MultiComm and PowerPlex serial port using an RS485 bus and then converts the register values to analog signals proportional to these measurements.

Using multi-drop RS485 provides for several useful configurations. The RS485 bus allows for configurations with multiple instruments with cable runs up to 4000’. This distributed architecture also allows hybrid configurations for use with mixed analog and serial solutions. Another useful feature of the distributed architecture is that the MultiComm and PowerPlex instruments can continue to be used, at no additional costs, when later upgrading to a serial communications network. The AOC is equipped with 8 analog outputs, using either 0-1mA or 4-20mA signals.
