UNSPSC 32101611: Programmable array logic PAL

UNSPSC 32101611 Programmable array logic PAL is a Commodity code that encompasses programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) system components, digital valve positioners, and related industrial automation equipment. State and local governments procure these components primarily for water treatment plant modernization, process control upgrades, and facility automation projects. Recent solicitations show water utilities replacing legacy PLC architectures (Modicon 984s, GE iFix systems) with current platforms (Modicon M580, Schneider Electric AVEVA) and procuring associated programmable devices, HMI terminals, network infrastructure, and integration services. The issuing bodies include municipal water districts, city departments of watershed management, municipal purchasing offices, and independent school districts, with water utilities representing the dominant buyer segment. The City of Austin Purchasing Office appears as a repeat buyer, posting multiple quotation requests for valve positioners and emissions monitoring equipment; the City of Atlanta Department of Watershed Management has posted related SCADA upgrade solicitations; and West Basin Municipal Water District is actively soliciting PLC replacement services.

Recent activity concentrates in Texas, Georgia, California, and Florida. Representative opportunities include West Basin Municipal Water District's RFP for Torrance Refinery Water Recycling Plant Programmable Logic Controller Replacements (due November 5, 2026), requiring replacement of three Modicon controllers with M580 processors, PLC programming, HMI development, and Factory and Site Acceptance Testing; the City of Santa Fe's RFP FY26RFP036 for PLC replacement and SCADA modifications at Buckman Direct Diversion water treatment sites (RFP deadline December 18, 2025, with proposals weighted 35 percent on scope and expertise, 30 percent on cost, and 25 percent on interview); and the City of Austin's recent IFQ for a digital valve positioner (due October 20, 2026), which initially targets certified small businesses and M/WBEs before public posting. The City of Atlanta issued May 2026 pre-advertisement notices for parallel SCADA modernization projects at Hemphill and Chattahoochee Water Treatment Plants, each requiring comprehensive system upgrades, integration with existing infrastructure, Factory Acceptance Testing, and personnel training across 360-day implementation windows. Most recent opportunities use RFP, RFQ, and IFB notice types, with response dates clustered in October 2026 and contract terms typically spanning one to two years with renewal options.
