Industrial 6634744K1 Analog Slave MV TC Module

Bailey 6634744K1 is an Infi90/Network 90 analog slave module designed for Bailey Infi90, ABB Symphony, and Harmony control systems. Known in the field as the Network 90 Analog Slave MV/TC module (NASM02) and also cataloged as IMASM02 in several listings, it provides input interfacing for millivolt and thermocouple signals to the central controller via the Network 90 backbone. The assembly number 6634744K1 identifies the unit used in ABB Bailey Symphony PLC boards (for example TK2279-3) and it is compatible with Bailey/ABB Infi90 Open Process Control configurations, enabling accurate sensor data acquisition across the analog network. This module is part of the Bailey/Infi90 analog input/slave family and is used to extend the system’s ability to monitor temperature sensors and low-level voltage signals in industrial automation environments.
