The NDSM05 is a high-density Digital Slave Module developed by ABB for the Bailey INFI 90 and Net 90 Distributed Control Systems (DCS). It is designed to acquire and process multiple 24V DC digital input signals from field devices such as limit switches, push buttons, relays, and proximity sensors.
The module supports up to 64 discrete input channels in a single slot, making it an efficient and compact solution for industrial automation systems requiring large-scale signal monitoring. With optical isolation technology and a fast response time of less than 5 milliseconds, the NDSM05 ensures reliable signal transmission, noise immunity, and real-time system performance in demanding industrial environments.
The NDSM05 is widely used in power generation, water treatment, petrochemical, and metal processing industries where legacy ABB Bailey INFI 90 systems remain operational.
The primary function of the NDSM05 is to collect digital status signals from field devices and transmit them to the ABB Bailey INFI 90 or Net 90 controller for monitoring and control purposes.
The module continuously scans input channels and converts field device status changes into data signals readable by the DCS controller. Its fast response capability enables accurate detection of critical events and supports time-sensitive industrial operations.
The optical isolation feature enhances system reliability by preventing electrical interference from affecting the control system backplane. This makes the module particularly suitable for industrial environments with high electrical noise levels.
