UNSPSC 39122331: Control relay

UNSPSC 39122331 Control relay, a Commodity code, encompasses electrical control components and relay assemblies that state and local governments procure for facility operations, water treatment systems, and infrastructure upgrades. Recent solicitations show demand for control relays embedded in larger electrical system replacements, motor control center upgrades, and programmable logic controller installations rather than as standalone components. The issuing bodies span water districts, municipal utility authorities, school districts, and county governments across multiple states, with water reclamation facilities, booster stations, and airport infrastructure representing primary use cases. Control relays appear within broader electrical modernization efforts—notably motor control center replacement, soft starter installations, PLC system upgrades, and switchgear replacements—where they function as part of integrated control systems rather than discrete line items.

Recent opportunities show heaviest activity in California, Florida, and Oregon. The Eastern Municipal Water District (Riverside County, California) solicited a medium voltage soft starter installation at Auld Road Booster Station (RFP, May 9, 2026 response) that integrates control relays into a 2400V system with CR2-CR6 control relays and time delay relay functionality. Orange County, Florida's Eastern Water Reclamation Facility Electrical and Mechanical Upgrades (IFB Y26-604, April 30, 2026 response) called for replacement of protective relays with Schweitzer microprocessor-based relays as part of a generator switchgear modernization. West Basin Municipal Water District (Torrance, California) issued an RFB for TRWRP 93 Motor Control Center Replacement (March 31, 2026 response) that includes complete MCC demolition and installation with associated relay and control system integration. The City of Santa Fe's PLC Replacement and SCADA Modification project (RFP FY26-RFP-036, January 9, 2026 response) targets four legacy controller replacements using Schneider Electric systems. These water and utility sector procurements dominate the code's recent activity, suggesting control relays are primarily specified as components within larger capital projects rather than routine maintenance buys.
