Description
1. Product Title
ABB Bailey IMASO01‑ 14‑Channel Analog Output Slave Module, INFI‑90 DCS
2. Product Overview
IMASO01 is a slave‑type analog output module for ABB Bailey INFI‑90 distributed control system. It provides 14 independent analog output channels to drive control valves, positioners and other 4‑20 mA / 1‑5 VDC field final elements. Communicates over INFI‑90 control bus with master processor modules. Each channel supports software‑selectable current or voltage mode, built‑in short‑circuit protection and over‑current limiting. Channel‑to‑power‑bus isolation reaches 1500 VDC. It is single‑slot Eurocard for INFI‑90 mounting unit. End‑of‑life / obsolete, only for spare‑part replacement for legacy power‑plant and petrochemical INFI‑90 installations。
