NTCS02 is ABB Bailey's termination unit for the Network 90 and Infi 90 distributed control systems, serving as the controller‑station termination point for field I/O. It interfaces with IMCIS02, IMQRS02, and IMRIO02 modules, and can be daisy‑chained with other Bailey termination units such as NTCS04 and NTRL01/02/03 to extend the I/O network. It weighs about 0.95 lb and is rated for 3 A at 24 VDC and 1 A at 24/125 VDC, with alternate identifiers including PNTCS02 and YNTCS02. ABB Bailey lists NTCS02 as discontinued, reflecting its status in legacy Infi 90/Network 90 installations.
