UNSPSC 39122322: Direct current voltage relay

A static relay that uses semiconductor. It is a relay that protects device or line by cutting off circuit or sounding alarm through highly sensitive detection of abnormal status of voltage during operation of direct current network system with capacity of less than DC300V.

UNSPSC 39122322 Direct current voltage relay is a Commodity-tier code that in recent state and local solicitations covers motor control centers, control panels, and electrical equipment bundles serving water, wastewater, and utility infrastructure operations. The code's scope extends beyond discrete DC voltage relays into broader electrical control assemblies — specifically motor control centers (MCCs) for pump stations and water treatment facilities, fabricated control cabinets with integrated relays and starters, and programmable logic controller (PLC) and supervisory control and data acquisition (SCADA) system replacements that incorporate voltage regulation and relay logic. State and local water utilities, county utilities departments, and special-purpose districts are the primary issuing bodies, with county commissioners and municipal utility agencies appearing repeatedly. Recent activity shows procurement for complete MCC replacement projects (Hillsborough County, West Basin Municipal Water District, Riverside County, Bay County, City of Bartow), PLC and SCADA modernization tied to control system upgrades (City of Santa Fe for water treatment), pump station control panel fabrication with UL 508A certification (Hillsborough County), and open-ended electrical equipment and parts supply contracts (Northside Independent School District). Scope generally includes factory acceptance testing, detailed shop drawings, programming, installation labor, 24/7 emergency support, and operator training where applicable.

Geographic activity concentrates in Florida (Hillsborough County, Bay County, City of Bartow, City of Tampa, City of Orlando) and California (West Basin Municipal Water District, Riverside County), with additional recent solicitations in New Mexico (City of Santa Fe) and Texas (Northside Independent School District), plus a Sourcewell cooperative vehicle covering multiple states. Representative opportunities include Hillsborough County's ITB 26-00393 for pump station control panels and enclosures, estimated $3.66 million over two years with bids due September 29, 2026; West Basin Municipal Water District's RFB for TRWRP 93 Motor Control Center Replacement in Torrance, California, with electronic bids due March 31, 2026 and mandatory pre-bid meeting on March 12, 2026; and City of Santa Fe's RFP FY26-RFP-036 for PLC replacement and SCADA modifications across four water treatment sites, with proposal submissions via OpenGov due December 18, 2025. The City of Tampa's single-source procurement (solicitation 26X01899) for Solcon Soft-Start replacement parts and services closed October 2, 2026. Water infrastructure modernization and equipment replacement cycles are driving recent demand.
