Industrial NASM03 Analog Slave Module

ABB Bailey NASM03 Network 90 Analog Slave Module is a dedicated analog slave interface for the Bailey INFI 90 / Net 90 distributed control system, providing a reliable means to bring analog signals from field instrumentation into the networked control processor. Identified by model type 6634416D1, the NASM03 belongs to the ABB Bailey Net 90 family and is designed as a single-slot module that slides into the Network 90 expander bus; it is intended to be installed adjacent to an Analog Master Module (AMM) or to other Analog Slave Modules, with up to eight slave modules supported per Master and bus termination managed by the NTAI03 termination unit. The NASM03 processes up to eight isolated RTD analog input signals, conditioning those signals for high-level processing by the Analog Master and ensuring signal integrity across the expander bus. In operation, these RTD inputs enable precise temperature measurement and monitoring in process control, with the NASM03 serving as the interface point between field sensors and the Bailey control network. Physical dimensions are listed as 188 x 51 x 130 mm and weight around 0.689 kg, reflecting its compact, single-slot form factor suitable for standard industrial enclosures and DIN rail or rack installations.
