Industrial NASI02 NAS102 Analog Slave Input Module

The NASI02 NAS102 Network 90 Analog Slave Input Module from ABB Bailey is a 15‑channel analog input slave for Network 90/Infi 90 systems, feeding field signals into the Multi‑Function Controller (MFC) or Processor. Each of its 15 channels is configured independently to accept common process signals, with per‑channel ranges including 4–20 mA and voltage options such as 1–5 VDC, 0–1 VDC, 0–5 VDC, 0–10 VDC, and -10 to 10 VDC, enabling flexible integration with Bailey smart transmitters and other field devices. The module performs analog‑to‑digital conversions on every input channel and provides the digital data to the MFC/processor for control and monitoring. For service and configuration, a handheld STT02 can be connected via an adapter jack on the slave faceplate to issue transmitter commands. As a Network 90 analog slave input module, NASI02/NAS102 sits in the Bailey Infi90 ecosystem to capture 15 analog signals from the field and relay them to master modules across the Network 90 bus.
