UNSPSC 39121523: Timer controls

UNSPSC 39121523 Timer controls is a Commodity code that in practice spans a much broader scope of industrial control and automation equipment than its name suggests. Recent state and local solicitations under this code reflect procurement of supervisory control and data acquisition (SCADA) systems, programmable logic controller (PLC) and human-machine interface (HMI) upgrades, electrical switchgear and protective relay installations, automated lighting control systems, and related instrumentation and controls infrastructure. State and local water utilities dominate the recent activity, with the City of Gallup, New Mexico and the City of Tucson appearing as repeat buyers. County and special-purpose districts also solicit under the code—Orange County, Florida's wastewater reclamation facility and DeKalb County, Georgia each issued capital upgrades involving control system modernization. State departments contribute occasional activity; the Washington State Department of Ecology posted a maintenance contract covering preventative and corrective work on electrical equipment and control subsystems.

The code shows activity concentrated in the Southwest and Southeast. The most recent opportunity is the City of Gallup's RFP 2025202603 for a comprehensive SCADA System Upgrade across 46 water system locations, issued as an RFP with a December 18, 2025 response date, emphasizing new fiber optic backbone deployment and replacement of legacy radio systems with modern supervisory and real-time data acquisition capability. Orange County, Florida issued IFB Y26604 in April 2026 for Eastern Water Reclamation Facility electrical and mechanical upgrades totaling multiple millions in switchgear, generator controls, and PLC/HMI system conversions, due April 30, 2026. The City of Tucson posted RFP 240048 for annual requirements fabrication of UL508A-rated station control panels for its water department, with an estimated annual spend of approximately $980,000 and in-state fabrication required. The Washington State Department of Ecology's IFB 2618ADM for electrical maintenance services at its headquarters facility, due July 20, 2026, reflects smaller-dollar preventative work and emergency repair contracting alongside capital projects. Geographic spread includes New Mexico, Arizona, Florida, Georgia, and Washington; no other states appear in the recent block.
