USDA ARS is seeking a complete controls upgrade for the Micro Gin at its Cotton Ginning Research Unit in Stoneville, Mississippi.
- **Government buyer:** U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS); the documents identify the Cotton Ginning Research Unit, USDA ARS AFM APD, and Research, Education, and Economics.
- **Procurement:** Supply and install a motor control center (MCC), programmable logic controller (PLC), human-machine interface (HMI), and related electrical equipment to replace existing hardwired controls. USDA provides the motors.
- **OEMs named:** **ABB Electrification U.S.; Schneider Electric; Eaton; Siemens; Rockwell Automation (Allen-Bradley); Mitsubishi Electric; Fuji Electric; General Electric; and Omron.** Named examples include Schneider M340, Allen-Bradley CompactLogix 5380, Siemens SIMATIC S7-1500, Omron NX1P2, Eaton C440 overload relays, Schneider Altivar ATV340, Eaton Power XL DX1, and Mitsubishi FR-A800. Some substitutions require client pre-approval.
- **Main equipment:** One MCC designed for 400 connected horsepower, with at least 600 A bus capacity, for a 480 V, 60 Hz, three-phase corner-grounded delta system; one PLC; HMI capacity to display 50 motor stations; one stand-alone motor-control console; and VFDs for motors designated in the motor schedule. The MCC includes space for four future compartments.
- **Controls and electrical scope:** PLC I/O requirements are 80 discrete inputs, 86 discrete outputs, 26 analog inputs, and 20 analog outputs, with 20–25% spare I/O. Provide 120/240 V single-phase distribution, a 600 A main, wiring, conduit, cable trays, connections, programming, and integration. The SOW describes using the existing 45 kVA transformer for distribution as required; an alternate MCC service arrangement is also described.
- **Notable requirements:** The HMI must support process displays, alarms, trends, motor controls, and production records, and show 50 motor start/stop stations on one or two screens. The console must be NEMA 4 steel and include an emergency stop, key-lock On/Off switch, and Manual Re-Set button. Equipment must be suitable for the facility’s dusty, humid, temperature-variable, and electrically noisy environment.
- **Services:** Remove existing controls and wiring; install and integrate equipment; perform factory and field testing, commissioning, and adjustments; and provide two workdays of training for up to five owner representatives. Factory testing must follow applicable ANSI, NEMA, and UL standards.
- **Schedule information:** PLC and HMI delivery is required within 120 days after contract acceptance, and the SOW sets a completion deadline. The sources-sought notice is market research, not a solicitation or request for proposal.
