Ovation 1C31206G01 4 Slot Rack Module Base Assembly

The Ovation 1C31206G01 is a robust and compact 4-slot rack module base assembly developed by Emerson for the Ovation Distributed Control System (DCS). As a critical part of Ovation’s modular I/O system architecture, this base assembly provides structural and electrical support for installing various I/O modules such as analog input/output, digital input/output, servo drivers, and control modules.

Designed for flexibility and reliability, the 1C31206G01 rack houses up to four plug-in modules, which connect via a secure backplane interface. It features integrated signal distribution pathways, power delivery, and backplane communication lines. With its industrial-grade construction and simple plug-and-play module accommodation, this rack base is ideal for both new installations and system expansions in harsh industrial environments.

Product Specifications

Product Applications

The 1C31206G01 is used wherever compact I/O rack systems are needed within the Ovation DCS platform. It supports both field control and central control cabinet applications, and is commonly found in:

• Power Plants (Thermal, Nuclear, Hydro)

  Used for organizing I/O modules related to turbine controls, boiler systems, and generator monitoring.

• Chemical and Petrochemical Industries

  Ideal for control panels managing process signals, field devices, and safety interlocks.

• Oil & Gas Facilities

  Supports wellhead control, compressor systems, and pressure/temperature monitoring modules.

• Water & Wastewater Treatment Plants

  Enables modular installation of valve control, sensor acquisition, and actuator output modules.

• Steel, Mining, and Pulp & Paper Plants

  Houses discrete and analog I/O modules for machinery control, chemical dosing, and automation sequences.

• System Expansion Projects

  Deployed for adding new I/O capacity without the need for a full cabinet overhaul.

Frequently Asked Questions (FAQ)

1. What types of modules can be installed in the 1C31206G01 rack?

The rack supports a wide range of Ovation I/O modules, including analog input/output, digital input/output, servo drivers, valve positioners, and specialty modules.

2. Does the rack include a power supply module?

No. Power is delivered from a centralized Ovation power module via the backplane interface. The rack itself does not generate power.

3. Is it possible to mix different types of modules in one rack?

Yes. Any combination of supported I/O and function modules can be installed in the four available slots, as long as power and system capacity allow.

4. How is the rack mounted in a control cabinet?

The chassis features standard mounting holes for either back-panel or DIN rail mounting, depending on system requirements.

5. Are the slots keyed to prevent incorrect module installation?

Yes. Each slot uses edge card connectors that are keyed to match specific module types, preventing mismatches.

6. Can modules be hot-swapped in the 1C31206G01 rack?

No. Modules should only be inserted or removed when the system is powered down to avoid damage or signal errors.

7. Is this rack compatible with both legacy and current Ovation modules?

Yes. It maintains backward compatibility with earlier generation modules and supports modern Ovation releases.

8. How do I ground the rack during installation?

A dedicated grounding point is provided on the chassis, which should be connected to the control cabinet’s common ground.

9. Does the rack provide any shielding against EMI or electrical noise?

Yes. The metal enclosure and internal design help shield sensitive signals from electromagnetic interference.

10. Can this rack be used in both centralized control panels and remote I/O stations?

Absolutely. Its compact form factor makes it suitable for central cabinets as well as distributed control points closer to the field devices.
