Product Description
The ABB Bailey NLSM01 is a Loop Storage Module specifically designed for use in the INFI 90 Distributed Control System (DCS). Integrated within the NCIU02 interface unit, the NLSM01 temporarily stores data collected from the plant loop before transferring it to a connected computer or control system. It ensures high-reliability data buffering in critical industrial automation environments.
