ABB IMDSI02-R Digital Input Module Infi 90

ABB Infi 90 IMDSI02-R Digital Input Slave is a 16‑channel digital input module for the Infi 90 distributed control system, organized as two groups of eight inputs to bring field signals—such as contacts or solenoids—into the control network. It mounts in a Module Mounting Unit (MMU) and communicates with a master module via the slave expander bus, powered from +5 VDC on P1 with a supply current of 80 mA. The module provides 16 front‑panel LEDs to indicate input status, with field wiring entering through a termination unit connected to connector P3. Twelve inputs are isolated from each other, while the remaining two input groups share common positive input lines to simplify wiring and diagnostics.
