IMFEC12 15-Channel Analog Input Module | ABB INFI 90 / Symphony DCS
The ABB IMFEC12 is a 15-channel analog input submodule designed for ABB Bailey INFI 90 and Symphony / Symphony Harmony distributed control systems. It acquires continuous process signals from field transmitters and sensors, then converts them into digital data for DCS controllers.
The module typically supports multiple analog signal types, including 4–20 mA, 1–5 V DC, thermocouple, and RTD inputs, making it suitable for temperature, pressure, flow, and level measurement applications. It is widely used in power generation, petrochemical, metallurgy, water treatment, and other process industries that require stable and accurate analog signal acquisition.
Some inquiries may list this module as IMFECI2. The correct ABB Bailey part number is commonly referenced as IMFEC12, so compatibility should be confirmed by label photo, system model, and slot configuration before ordering.
Supports multi-channel process signal acquisition for DCS controllers.
Typically supports 4–20 mA, 1–5 V DC, thermocouple, and RTD inputs.
Designed for ABB Bailey INFI 90, Net 90, and Symphony Harmony DCS systems.
Channel isolation helps reduce interference from field wiring and power disturbances.
Front-panel indicators help maintenance teams quickly identify module and channel status.
Ideal for legacy DCS maintenance, plant upgrades, and long-term inventory stocking.
