UNSPSC 32151706: Programmable Logic Controller Power Supply

UNSPSC 32151706 Programmable Logic Controller Power Supply is a Commodity code. State and local governments soliciting under this code are actually buying PLC replacement services, SCADA system modernization and integration, control system components, and ancillary industrial automation equipment — not isolated power supplies alone. Recent solicitations show water utilities, energy centers, and municipal agencies procuring comprehensive PLC upgrades bundled with programming, integration, testing, training, and commissioning services. Issuing bodies include municipal water districts (West Basin Municipal Water District), city public utilities departments (City of Atlanta Department of Watershed Management, City of Santa Fe), municipal purchasing offices (City of Austin Purchasing Office), county utility authorities (Sarasota County), and independent school districts (Northside Independent School District). The code sees activity across multiple issuing-body types, with water treatment plant modernization driving the highest-value recent solicitations.

Geographic activity concentrates in Texas, California, and Georgia. Recent solicitations include the West Basin Municipal Water District requesting RFP proposals for Torrance Refinery Water Recycling Plant Programmable Logic Controller Replacements with a response deadline of November 5, 2026, covering replacement of Modicon controllers with Modicon M580 processors, PLC programming, HMI development, and Factory and Site Acceptance Testing; the City of Santa Fe (on behalf of Buckman Direct Diversion) seeking RFP responses for PLC replacement and SCADA modifications across four critical water system PLCs with an evaluation framework weighting scope expertise at 35 percent and cost at 30 percent, with local preference available to Santa Fe resident businesses; the City of Atlanta Department of Watershed Management soliciting competitive proposals for SCADA improvements at both the Chattahoochee and Hemphill Water Treatment Plants with 360-day project timelines, requiring vendors to demonstrate five years of comparable integration experience and three prior water or wastewater treatment facility ControlLogix upgrades; and the City of Austin Purchasing Office requesting quotations for digital valve positioners and related components (IFQ 1100 AGM1029, due October 20, 2026) with initial SBE and M/WBE preference.
