OVATION 1C31174G04 Ovation Loop Interface Electric Drive

This module typically supports 8 individually isolated analog output channels and is designed to convert digital control signals into standard analog outputs (e.g., 4-20mA), allowing seamless control of final elements like valves, dampers, and positioners. As part of the Ovation system’s I/O subsystem, it benefits from Emerson’s robust engineering, diagnostic capabilities, and long lifecycle support.
