The EMERSON Ovation 1C31116G04 is an analog input module designed for high-precision signal acquisition in Emerson’s Ovation distributed control system (DCS), widely used in power generation and process industries.
1. Core Functions
Analog Signal Processing:
Accepts 4–20mA, 0–10V, or thermocouple/RTD signals from field sensors (e.g., pressure transmitters, temperature probes).
Provides 16-bit resolution for high-accuracy measurements (±0.1% typical).
Isolation & Noise Immunity:
Features channel-to-channel and system isolation to prevent ground loops and EMI interference.
Includes built-in surge protection (IEC 61000-4-5) for harsh electrical environments.
Real-Time Diagnostics:
Detects open-circuit, over-range, or sensor failures and triggers alarms in the Ovation DCS.
Supports hot-swapping for maintenance without system shutdown.
Seamless Ovation Integration:
Directly interfaces with Ovation controllers for closed-loop control (e.g., turbine regulation, boiler control).
Configurable via Ovation Developer Studio software for scaling, filtering, and alarm thresholds.
2. Key Applications
Power Plants: Monitors steam pressure, turbine vibrations, and fuel flow rates.
Oil & Gas: Measures pipeline pressures, tank levels, and compressor temperatures.
Water Treatment: Tracks pH, flow rates, and chemical dosing.
