UNSPSC 39122334: Relay board or multiple relay module

UNSPSC 39122334 Relay board or multiple relay module is a Commodity code that state and local governments procure as components and subassemblies for electrical control systems, motor starters, switchgear, and water treatment infrastructure upgrades. Recent solicitations show governments buying relay modules and related electrical control components embedded in larger systems—motor control centers, programmable logic controllers, soft starters, and facility electrical upgrades—rather than as standalone discrete parts. Issuing bodies span water utilities (Eastern Municipal Water District, Hillsborough County Water Resources, Orange County), school districts (Northside Independent School District, Bibb County Public Schools), municipalities (City of Phoenix, City of Santa Fe, City of Charlotte), and special-purpose agencies (West Basin Municipal Water District). Repeat buyers include Hillsborough County Water Resources Department, which has posted multiple electrical component solicitations in the recent window.

Geographic activity concentrates in Florida (Hillsborough County, Orange County, Monroe County), California (West Basin, Eastern Municipal Water District in Riverside County), and Texas (Northside Independent School District in San Antonio), with secondary activity in Oregon, Georgia, and New Mexico. Representative recent opportunities include Eastern Municipal Water District's solicitation for a medium voltage soft starter installation at Auld Road Booster Station (RFP RFPAR3928, due May 9, 2026), which specified a 2400V/97A/450HP MVSS with installation and training; Orange County, Florida's invitation for bids on Eastern Water Reclamation Facility electrical and mechanical upgrades (IFB Y26-604, due April 30, 2026), encompassing switchgear modifications, generator upgrades, and protective relay replacement; and the City of Santa Fe's request for proposals for programmable logic controller replacement and SCADA modifications (RFP FY26-RFP-036, due January 9, 2026), requiring Schneider Electric control system integration across water treatment sites. Hillsborough County Water Resources Department's ITB for mercury float switches (ITB-26-00123, due February 24, 2026) and bid for Square D contact kits (ITB-26-00123, due February 24, 2026, estimated value $184,000) exemplify narrow component procurement within control systems.
