ABB IMDSO04 Bailey INFI 90 Digital Slave Output Module
The ABB IMDSO04 is a 16-channel digital slave output module designed for the ABB Bailey INFI 90 Distributed Control System (DCS). It translates control commands from the central system processor into discrete on/off switching signals, operating external field devices such as relay coils, solenoid valves, and indicator lamps through solid-state output circuitry.
Hardware Interface and Backplane Integration
The IMDSO04 mounts into a single slot of a standard INFI 90 Module Mounting Unit (MMU) and communicates with the system master via the internal expander bus. Internal logic power is supplied by the rack at +5 VDC (135 mA typical, 200 mA maximum), while output circuits draw a separate operating current ranging from 150 mA typical to 250 mA maximum.
Front-panel status LEDs provide immediate visual monitoring for both individual channel switching states and overall module operational health.
Output Ratings and Electrical Characteristics
Each of the 16 solid-state open-collector outputs is rated to drive 24 VDC field loads with a maximum load current of 250 mA per channel. Under operating conditions up to 70 deg C, maximum off-state leakage current is limited to 10 uA, and maximum on-state voltage drop is 2.4 V.
To protect system backplane architecture from transient voltages and ground loops, the module provides 300 Vrms electrical isolation between output circuits and internal logic circuitry, as well as channel-to-channel isolation. The circuitry also meets ANSI/IEEE C37.90A-1974 surge withstand capability specifications.
