ABB Bailey IIMSM01 Serial I/O Module

This serial I/O module connects RS-232 and RS-422 devices to ABB Bailey systems. You will find the ABB Bailey IIMSM01 Serial I/O Module interfacing with barcode scanners, printers, and weighing scales. Its dual-port design supports two independent serial devices simultaneously.

Technical Specifications

This module contains two fully isolated serial communication ports. You can also locate eight configuration DIP switches for protocol selection. The ABB Bailey IIMSM01 Serial I/O Module stores no battery energy for configuration retention. Instead, it uses non-volatile flash memory for all communication settings. Therefore, this module never requires any routine battery replacement.

Communication Details

The ABB Bailey IIMSM01 Serial I/O Module draws its operating power from the INFI 90 bus backplane. You can configure each port independently for different protocols and baud rates. The module buffers incoming serial data before transmitting it to the system controller. Moreover, the eight DIP switches set communication parameters without software tools. This design allows quick field configuration using only a small screwdriver.

Mechanical Integration and Mounting

You must insert the ABB Bailey IIMSM01 Serial 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 0.47 kilograms for straightforward handling. Furthermore, the module includes LED indicators for transmit and receive activity on both ports.

Environmental and Storage Guidelines

You should store this ABB Bailey IIMSM01 Serial 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 strong electromagnetic fields. Because the module uses solid-state components only, it requires zero regular maintenance over its service life.
