Description

Product Description

The NTCL01-A is a dedicated communication termination module developed by ABB for Bailey INFI 90 and Symphony Plus distributed control environments. It functions as the physical endpoint for INFI-NET communication loops, ensuring reliable signal continuity between network interface modules and the plant-wide control communication backbone.

This unit is installed within control cabinets and serves as an essential interface element for linking loop communication modules and network slave devices into a stable and structured DCS communication architecture.
