ABB Bailey INBIM02 Interface – Modbus RTU/ASCII

This interface module bridges communication between ABB Bailey controllers and external devices. You will find the ABB Bailey INBIM02 Interface Module translating data formats for seamless system integration. Its compact single-wide design fits into any standard INFI 90 rack slot.

Technical Specifications

This module contains one primary serial port and one auxiliary programming port. You can also locate six configuration DIP switches for protocol selection. The ABB Bailey INBIM02 Interface 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 INBIM02 Interface Module draws its operating power from the INFI 90 bus backplane. You can select RS-232 or RS-485 operation using the six DIP switches. The module buffers incoming messages before forwarding them to the system controller. Moreover, the auxiliary programming port allows direct configuration without network access. This design simplifies initial setup and field troubleshooting procedures.

Mechanical Integration and Mounting

You must insert the ABB Bailey INBIM02 Interface 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 0.45 kilograms for straightforward handling. Furthermore, the three status LEDs indicate power, transmit, and receive activity.

Environmental and Storage Guidelines

You should store this ABB Bailey INBIM02 Interface 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.
