ABB Bailey IMDSM05 Digital I/O Module

This digital I/O module provides discrete signal processing for ABB Bailey systems. You will find the ABB Bailey IMDSM05 Digital I/O Module monitoring field contacts and driving output relays. Its mixed configuration supports both inputs and outputs in a single unit.

Technical Specifications

This module contains sixteen digital channels configurable as inputs or outputs. You can also locate two status LED bars for visual channel indication. The ABB Bailey IMDSM05 Digital I/O Module stores no battery energy for configuration retention. Instead, it uses solid-state optocouplers for all signal isolation purposes. Therefore, this module never requires any routine battery replacement.

Channel Configuration Details

The ABB Bailey IMDSM05 Digital I/O Module draws its operating power from the INFI 90 bus backplane. You can configure each channel as either an input or output through software settings. Input channels read dry contacts or 24 VDC field signals reliably. Output channels switch DC loads up to 0.5 amps without external relays. Moreover, the optocouplers provide 1500 VDC isolation between field and logic sides.

Mechanical Integration and Mounting

You must insert the ABB Bailey IMDSM05 Digital I/O Module carefully into any standard INFI 90 slot. After full insertion, secure the module using the top and bottom metal retaining clips. The module measures exactly 25.5 centimeters in length and 3.2 centimeters in width. Its total weight reaches approximately 0.46 kilograms for straightforward handling. Furthermore, the module includes a front extraction handle and two LED status bars.

Environmental and Storage Guidelines

You should store this ABB Bailey IMDSM05 Digital I/O Module in an anti-static bag away from moisture. The module operates reliably between 0°C and +60°C ambient temperature. Likewise, keep the unit away from conductive dust or corrosive atmospheres. Because the module uses solid-state switching only, it requires zero regular maintenance over its service life.
