Emerson Ovation 1C31147G01 Pulse Accumulator Module

The Emerson Ovation 1C31147G01 is a dedicated pulse accumulator module for Ovation DCS distributed control system. It receives pulse signals from flow meters, encoders and speed sensors, completes high‑speed pulse counting and frequency measurement, and transmits metering data to the Ovation controller for flow totalization and rotating‑speed monitoring.

This hot‑swappable rack‑slot I/O module provides multi‑channel pulse input interfaces with electrical isolation and channel‑level self‑diagnosis, fitted with front‑panel LED status indicators. It works with matched field termination assembly. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
