Processing and Communication Details

The ABB Bailey IMRCC02 CPU & Communication Module draws its operating power from the INFI 90 bus backplane. The main CPU executes ladder logic and function block programs continuously. You can connect a programming terminal to either serial port for online configuration. Moreover, the coprocessor handles all network message routing independently. This design offloads communication tasks from the main processor for faster control loops.

Mechanical Integration and Mounting

You must insert the ABB Bailey IMRCC02 CPU & Communication 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 0.55 kilograms for straightforward handling. Furthermore, the module includes a front extraction handle and status LED panel.

Environmental and Storage Guidelines

You should store this ABB Bailey IMRCC02 CPU & Communication 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 contains a lithium battery, dispose of it according to local regulations.
