WESTINGHOUSE 2D78559G01 Universal RTD Module – OVATION Distributed Control System
When a Universal RTD Module fails in a power plant or industrial process facility, the consequences are immediate and severe: temperature measurement loops go blind, process controllers lose critical feedback, and operators are forced into manual override — risking both equipment damage and unplanned downtime. In high-stakes environments such as turbine control, boiler management, and heat exchanger monitoring, a single failed RTD input card can cascade into a full unit trip. The WESTINGHOUSE 2D78559G01 is the precision component that keeps these measurement chains intact.
The 2D78559G01 occupies a foundational role within the WESTINGHOUSE OVATION Distributed Control System — one of the most widely deployed DCS platforms in global power generation and process industries. Engineered to accept multiple RTD input types with high-resolution analog conversion, this module delivers the signal integrity and channel density that OVATION-based control architectures demand. Its installed base spans nuclear, fossil fuel, and combined-cycle power plants across North America, Europe, and Asia-Pacific, making it one of the most mission-critical I/O modules in the OVATION ecosystem.

Frequently Asked Questions
Q: Is the WESTINGHOUSE 2D78559G01 still in production?
A: The OVATION platform has transitioned through multiple ownership changes (Westinghouse → Emerson). Availability of new units may be limited. Konmask.com maintains stock of new surplus and tested refurbished units. Contact us for current availability.
Q: Can this module be used as a direct replacement without reconfiguration?
A: In most like-for-like replacement scenarios within the same OVATION system revision, the 2D78559G01 is a plug-compatible swap. However, we recommend verifying firmware compatibility with your system integrator or DCS engineer before installation.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a standard warranty on all tested refurbished units. Warranty terms are specified in the sales agreement. New surplus units carry OEM warranty where applicable.
Q: What is the lead time for international orders?
A: In-stock items typically ship within 3–5 business days after order confirmation. Lead time for sourced items varies; we provide an estimated delivery date at the time of quotation.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Yes. We support bulk procurement and long-term supply agreements for maintenance, repair, and operations (MRO) programs. Contact us to discuss volume pricing and stocking arrangements.
