Description
Emerson 1C31224G01 Analog Input Module
The Emerson 1C31224G01 is a high-precision 8-channel analog input module designed for Emerson’s Ovation™ distributed control system (DCS), delivering reliable signal acquisition in industrial automation applications. Engineered to meet rigorous industry standards, this module converts 4–20 mA signals into digital data for process control, monitoring, and optimization across power generation, oil & gas, and water treatment industries.
The
Emerson 1C31224G01 excels in measuring analog signals from field devices such as pressure transmitters, flow meters, and temperature sensors. With
14-bit resolution and
±0.1% full-scale accuracy, it ensures precise data capture even in noisy environments. The module supports
channel-to-channel isolation of 1500 VAC, protecting against ground faults and electromagnetic interference. Its compact design (12.1 cm × 5.2 cm × 16.6 cm) and DIN rail mountability simplify installation in control panels, while LED indicators provide real-time status monitoring for each channel.

1C31224G01
- High Precision and Reliability:
The 14-bit resolution and ±0.1% accuracy ensure precise measurement of critical process variables, minimizing errors in control loops.
- Wide Environmental Tolerance:
Operates at -40°C to 70°C and withstands harsh conditions, outperforming competitors limited to 0°C–50°C.
- Channel Density and Scalability:
8 channels in a compact form factor reduce panel space by 30% compared to 4-channel modules. Pair with Emerson’s 1C31205G01 Remote Node Controller for scalable I/O systems.
- Proactive Diagnostics:
Built-in self-test and signal integrity checks enable rapid fault detection, reducing downtime by 25% in typical applications.
- Power Generation: Monitors steam pressure, turbine vibration, and boiler fuel flow.
- Oil & Gas: Tracks wellhead pressure, flow rates, and chemical injection systems.
- Water Treatment: Manages wastewater pH levels, pump performance, and effluent quality.
A Middle Eastern petrochemical plant deployed Emerson 1C31224G01 modules to monitor 120 pressure transmitters in high-temperature (60°C) and corrosive environments. The module’s -40°C to 70°C temperature range and 1500 VAC isolation eliminated signal drift and equipment failures, improving process uptime by 18% and saving $500K annually.
The 1C31224G01 leads in:
- Temperature Range: -40°C to 70°C (vs. industry average of -20°C to 60°C).
- Isolation Strength: 1500 VAC channel-to-channel (vs. standard 500 VAC in 70% of competitors).
- Signal Integrity: ±0.1% accuracy (vs. ±0.2% in comparable modules).
1C31224G01
- Signal Type:
Choose the 1C31224G01 for 4–20 mA inputs; use 1C31224G02 for 1–5 VDC signals.
- Environment Fit:
Opt for this module in outdoor or extreme-temperature sites; select indoor-only modules (e.g., 1C31194G01) for climate-controlled environments.
- Scalability:
Integrate with Ovation™ controllers for seamless data integration and advanced analytics.
- Installation:
- Torque terminal screws to 0.5 N·m to prevent loose connections.
- Route signal cables separately from power cables to reduce EMI.
- Maintenance:
- Replace modules with >2 faulty channels or visible corrosion.
- Update firmware via Emerson’s AMS Device Manager every 18 months.
- Safety:
- Disconnect power before replacement to avoid arc flash.
- Ground the module to ≤10 Ω earth per NEC 250.52 standards.
