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.
