The ABB Bailey NSIM01 Serial Interface Module is a communication interface module used in the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It is designed to handle serial communication between control system modules and external or internal network devices, enabling reliable data exchange within the Bailey automation architecture.
In industrial control systems, many legacy devices still rely on serial communication. The NSIM01 provides a stable interface for these connections, supporting system integration, diagnostics, and data transfer between processors, I/O modules, and supervisory systems.
It is commonly found in long-life ABB Bailey installations in power plants, oil and gas facilities, and other process industries where robust and deterministic communication is required.
