The NASM02S analog slave module from ABB Bailey expands analog I/O capacity within INFI 90 and Net 90 control systems. Plant engineers add this module whenever a primary controller needs extra sensor channels. Consequently, it delivers reliable analog signal handling without replacing the main processor card.

Functional Overview
This module collects analog signals from field transmitters and converts them into digital values. Therefore, it extends the reach of the host controller into additional process loops. The NASM02S isolates each channel to reduce noise and ground loop interference. Meanwhile, its onboard energy storage stabilizes readings against transient voltage fluctuations.
Installation and Handling Notes
Always verify signal type and range before wiring the NASM02S to field instruments. In addition, check that channel addressing matches your configuration database. Tighten terminal screws evenly to prevent intermittent connections. Finally, calibrate each input point during commissioning.
