The ROC827 Remote Operations Controller is a microprocessor-based controller that provides the functions required for a variety of field automation applications. The ROC827 is ideal for applications requiring general logic and sequencing control; historical data archiving; multiple communication ports; Proportional, Integral, and Derivative (PID) control; and flow measurement on up to twelve meter runs. When attached to the ROC827, the ROC800-Series expanded backplanes provide the ROC827 with increased I/O capabilities.
