Emerson Ovation 1C31150G01 Pulse Accumulator Module

The Emerson Ovation 1C31150G01 is a local‑power negative‑common pulse accumulator module for Ovation DCS distributed control system. It receives pulse signals from flow transmitters, speed encoders and pulse‑type field instruments, performs pulse counting and frequency measurement, and uploads cumulative metering data to Ovation controller for thermal‑power‑plant process calculation and rotating‑equipment monitoring.

This hot‑swappable rack‑slot I/O module adopts negative‑common input mode, integrates channel‑level electrical isolation, hardware self‑diagnosis and front‑panel LED status indicators. It requires supporting field termination assembly for field‑loop wiring. It serves as critical aftermarket spare for power‑plant DCS cabinet maintenance, overhaul and hardware retrofitting projects.
