Introduction
The ABB Bailey NDSM01 Numeric Subordinate Input Module is a key component for distributed numeric data acquisition in industrial automation systems. Designed as a subordinate module, it offloads the main controller by handling local input processing while maintaining high precision and reliability. Its robust design, coupled with seamless integration into the INFI 90 platform, ensures accurate data collection and system scalability. Engineers can deploy the NDSM01 to extend control capacity without increasing central rack complexity, making it ideal for both retrofit and new installations.
