IMDSI14 16-Channel Digital Input Module | INFI 90 / Symphony DCS

The ABB IMDSI14 is a 16-channel digital input submodule designed for ABB Bailey INFI 90 and Symphony distributed control systems. It acquires on/off status signals from field devices such as switches, relays, limit switches, pushbuttons, valve position feedback, and motor running signals, then transmits them to the DCS controller for logic processing.

The module supports dry contact and wet contact inputs, typically compatible with 24 VDC industrial signals, and provides opto-isolation between channels to reduce the risk of electromagnetic interference affecting system stability. It is widely used in power generation, petrochemical, metallurgy, water treatment, and other process industries that require reliable discrete signal monitoring.

The IMDSI14 is typically installed in an INFI 90 / Symphony I/O rack or submodule slot and works together with compatible controller and interface modules. Exact revision, termination unit, and configuration requirements should be confirmed before ordering.
