Emerson Ovation 5X00070G04 Millivolt Analog Input Module

The Emerson Ovation 5X00070G04 is a hot‑swappable millivolt‑range analog input module for Ovation DCS distributed control system. It is specially designed for low‑level millivolt signals, supporting 20mV, 50mV and 100mV input ranges, performing high‑precision 14‑bit analog‑to‑digital conversion, and transmitting measurement data to Ovation controller for thermal‑couple and strain‑gauge‑based process monitoring in power‑plant automation systems.

This MK‑series rack‑slot I/O module contains 8 galvanic‑isolated channels, integrates channel fault diagnosis and front‑panel LED status indicators. It must be installed on Ovation I/O carrier chassis and cooperate with matched termination base hardware. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
