Supply of 69 controls and power distribution cubicles for ATLAS and CMS 2PACL CO2 detector cooling systems.

CERN intends to place a contract for the supply of 69 controls and power distribution cubicles for ATLAS and CMS 2PACL CO2 detector cooling systems, based on Schneider M580 redundant PLCs and interconnected with distributed I/O islands via a Schneider RIO loop in ring topology. The cubicles have different dimensions of H=1800 mm, D=400 mm, and W=600mm, 800 mm or 1000 mm depending on the variant. Deliveries are foreseen as a pre-series followed by two series batches over the course of a year from Q3 2022. Interested firms shall have a proven experience and competence in control cabinet fabrication and assembly, the design or review of designs of control cabinets, and wiring of Schneider I/O cards.
