PRODUCT INFORMATION
Product Overview
The ABB NLIM02 is a Loop Interface Module designed for Bailey INFI 90 distributed control systems. This plug-in module installs directly into standard INFI 90 or Network 90 rack backplanes. It receives operating power directly from the system backplane at +5 VDC. The unit manages communication between system controllers and field-level loop devices across the process network.
The module processes both analog and digital I/O loops from connected industrial field instrumentation. Its architecture supports retrofits and maintenance in legacy ABB-Bailey Network 90 and INFI-90 architectures. Operating within standard chassis slots, it maintains signal integrity across distributed control loops. Facilities deploy the module to preserve existing process control infrastructure without requiring major cabinet rewiring.
