1. General Specifications

• Brand & Model: Westinghouse (Emerson) 1C31233G04
• Type: Digital Input Module (Contact Closure Detection)
• System Compatibility: Emerson Ovation DCS
• Certifications: CE, UL (compliant with industrial safety standards)
• Version Variations: Part of the Ovation E-MOD series (e.g., 1C31233G01 for 24/48V DC, 1C31233G04 for 48V DC onboard power)

2. Functional Features

Event Recording

• SOE Capability: Records up to 10,000 events/second with 1 ms timestamp resolution for critical process changes, alarms, or operator actions.
• Event Storage: Supports 100,000 events (dependent on system configuration).
• Contact Inputs: 16 channels for detecting dry contact closures (e.g., switches, relays).

Input Parameters

• Contact Voltage:
  • Wetting Voltage: 48V DC (onboard power supply for open contacts).
  • Logic Voltage: 10V DC (activates opto-isolators when contacts close).
• Input Type: Dry contact (current-limited design prevents damage).
• Bounce Rejection: Built-in filtering to eliminate transient noise.

Power Supply

• Module Power: 48V DC (onboard auxiliary supply for contact wetting).
• Power Consumption: < 5W.

3. Physical Characteristics

• Dimensions:
  • Standard: 12.1 cm (W) × 2.5 cm (H) × 7.0 cm (D).
  • Alternative Sources: 11.9 cm × 2.9 cm × 9.5 cm (weight: 0.15 kg).
• Weight: ~0.71 kg (1.56 lbs).
• Mounting: DIN-rail or panel-mounted (compact design for space efficiency).

4. Communication & Interfaces

• Ovation Bus Integration: Direct connectivity with Ovation controllers and HMIs.
• Protocols: RS-485 (Modbus RTU), Ethernet (TCP/IP), and support for HART/Profibus (via optional modules).
• Data Transfer Rate: Up to 1 Mbps for real-time event synchronization.

5. Environmental Specifications

• Operating Temperature: -40°C to +70°C (ruggedized for harsh industrial environments).
• Humidity: 5–95% RH (non-condensing).
• Shock/Vibration Resistance: Compliant with IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock).
• Enclosure Rating: IP67 (dust- and water-resistant for outdoor or washdown areas).

6. Indicator Lights

• Power (P): Green LED confirms 48V DC supply.
• Communication (C): Green LED indicates healthy Ovation Bus connection.
• Fault (F): Red LED alerts to internal errors or ground faults (e.g., <5 kΩ impedance to earth).

7. Installation & Maintenance

• Wiring:
  • Terminals: 16-channel terminal block with common return lines (avoid grounding to prevent faults).
  • Diagrams: Refer to Emerson’s Ovation I/O Module Manual for pinouts and wiring guidelines.
• Hot-Swap: Supports module replacement without system downtime.
• Diagnostics: Built-in self-test and error logging for quick troubleshooting.

8. Applications

• Power Generation: Monitoring turbine trips, breaker operations, and relay status in substations.
• Water/Wastewater: Detecting pump failures, valve positions, and level switch events.
• Manufacturing: Tracking conveyor belt stops, machine alarms, and safety interlocks.
• HVAC: Logging critical events in building automation systems.

9. Compatibility & Redundancy

• Ovation System Integration: Works seamlessly with Ovation controllers (e.g., 5X00481G04) and engineering workstations.
• Redundancy Support: Configurable in redundant pairs for high-availability systems (requires Ovation’s redundancy modules).

10. Availability & Support

• Distributors: Authorized Emerson partners (e.g., Amikon, 6gcontrols).
• Warranty: Typically 1–2 years (varies by distributor).
• Technical Support: Firmware updates, configuration tools, and training via Emerson’s MyEmerson platform.

Important Notes

• Version-Specific Features: The 1C31233G04 is optimized for 48V DC onboard power, differentiating it from variants like the 1C31233G01 (24/48V DC).
• Safety Compliance: Ensure adherence to Ovation’s safety guidelines and local regulations during installation.
• Documentation: For precise technical details (e.g., pinouts, firmware versions), download the official Emerson Ovation 1C31233G04 Datasheet via the Emerson Support Portal.
