WESTINGHOUSE 1C31147G01 – Pulse Accumulator Module | Ovation DCS Platform
Engineering Background
The Westinghouse Ovation Distributed Control System (DCS) is a proven platform deployed across power generation, oil & gas, and process industries worldwide. Designed for mission-critical environments, the Ovation architecture demands I/O modules that deliver deterministic signal acquisition with zero tolerance for data loss. The 1C31147G01 Pulse Accumulator Module is a purpose-built component within this ecosystem, engineered to capture and accumulate high-frequency pulse signals from field instrumentation with hardware-level precision.
Product Positioning
The 1C31147G01 serves as the primary pulse counting interface for Ovation DCS controllers, enabling accurate totalization of flow, speed, and event-based signals. It is the preferred replacement and upgrade module for legacy Westinghouse WDPF and early Ovation installations requiring reliable pulse input capability. Konmask.com supplies this module from verified surplus and OEM-sourced inventory, fully tested and ready for immediate deployment.

Engineering Advantages
System Architecture & Signal Flow
The 1C31147G01 installs into a standard Ovation I/O module slot within the Ovation controller cabinet. Field pulse signals (dry contact closures or voltage pulses from flow transmitters, encoders, or proximity switches) are wired to the module’s terminal block. The module’s onboard accumulator hardware captures each pulse edge independently of the controller scan cycle, storing the running total in a dedicated register. On each Ovation scan cycle, the controller reads the accumulated count delta, resets the hardware register, and updates the process database — ensuring zero pulse loss even at high input frequencies. The accumulated value is then available to Ovation control strategies, historian, and HMI displays via the standard Ovation data highway.

Technical FAQ
Q: Is the 1C31147G01 compatible with both WDPF and Ovation DCS?
A: The 1C31147G01 is designed for the Ovation platform. WDPF compatibility depends on the specific backplane revision — contact us with your system details for confirmation.
Q: What is the maximum pulse input frequency this module can handle?
A: Maximum input frequency specifications are defined in the Westinghouse/Emerson 1C31147G01 datasheet. Contact our team for the full technical datasheet.
Q: Can this module be used as a direct replacement for a failed unit without controller reconfiguration?
A: Yes, in most cases a like-for-like replacement requires no controller reconfiguration. The Ovation system will recognize the module automatically upon insertion.
Q: Do you offer volume pricing for MRO stocking orders?
A: Yes. Volume discounts are available for orders of 3+ units. Submit your RFQ for a tiered pricing schedule.
