Description
Emerson 5X00499G01 Digital Input Module
The Emerson 5X00499G01 is a high-performance Digital Input (DI) Module designed for industrial automation systems, particularly Emerson’s Ovation™ distributed control system (DCS). Engineered to withstand harsh environments, this module delivers reliable monitoring of discrete signals in critical applications across power generation, oil & gas, and water treatment industries.
1. Product Description
The Emerson 5X00499G01 converts field-level switch statuses (e.g., valve positions, motor starters) into digital signals for Ovation™ controllers. With 16 isolated channels and 500 VDC channel-to-ground isolation, it ensures accurate data transmission in high-noise environments. The module supports 24 VDC/48 VDC inputs (selectable via jumper) and operates across -40°C to 70°C, making it suitable for extreme-temperature installations. Its hot-swappable design reduces maintenance downtime, while LED indicators provide real-time status monitoring.

3. Key Advantages and Features
- Dual Voltage Flexibility:
Supports both 24 VDC and 48 VDC inputs, eliminating the need for separate modules in mixed-voltage systems. - Extreme Environment Resilience:
Operates at -40°C to 70°C, outperforming competitors limited to 0°C–50°C. - High Channel Density:
16 channels in a compact design reduces panel space by 30% compared to 8-channel modules. - Proactive Fault Detection:
LED indicators for channel status and module health enable rapid diagnostics.
4. Application Areas and Case Studies
Industry Applications
- Power Generation: Monitors turbine emergency stop buttons and generator breaker states.
- Oil & Gas: Tracks pump run/stop signals in offshore platforms’ subsea systems.
- Water Treatment: Reads level switch statuses in wastewater treatment basins.
Case Study
A Canadian LNG facility deployed Emerson 5X00499G01 modules to monitor 480 ESD switches in subzero (-35°C) conditions. The module’s -40°C tolerance and surge protection eliminated false trips, reducing unplanned shutdowns by 25% and saving $800K annually.
5. Competitor Comparison
The 5X00499G01 leads in:
- Voltage Flexibility: Dual 24/48 VDC support (vs. single voltage in 60% of competitors).
- Isolation Strength: 500 VDC channel-to-ground (vs. standard 250 VDC).
- Temperature Range: -40°C to 70°C (vs. industry avg. -20°C to 60°C).

6. Selection Recommendations
- Voltage Matching:
Confirm field device voltage (24V/48V) and use jumpers to select the correct mode. - Environment Fit:
Choose the 5X00499G01 for outdoor/extreme-temperature sites; opt for indoor-only modules (e.g., 1C31178G01) for climate-controlled environments. - Scalability:
Pair with Emerson’s 1C31205G01 Remote Node Controller to scale to 96+ DI channels per node.
7. Usage Precautions
- Installation:
- Torque terminal screws to 0.5 N·m to prevent loose connections.
- Separate signal cables from power cables by 10 cm to reduce EMI.
- Maintenance:
- Replace modules with >3 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.
