ABB Bailey IMRAI11 Analog Input Module

This analog input module converts field sensor signals for ABB Bailey INFI 90 systems. You will find the ABB Bailey IMRAI11 Analog Input Module processing 4-20 mA and 0-10 VDC signals from transmitters. Its high-density design packs sixteen channels into a single-wide slot.

Technical Specifications

This module features sixteen single-ended analog input channels for field connections. You can also locate two status LEDs for module health indication. The ABB Bailey IMRAI11 Analog Input Module stores no battery energy for configuration retention. Instead, it uses non-volatile memory for all calibration and range settings. Therefore, this module never requires any routine battery replacement.

Signal Conversion Details

The ABB Bailey IMRAI11 Analog Input Module draws its operating power from the INFI 90 bus backplane. You can configure each input channel for current or voltage using software commands. The module samples all sixteen channels sequentially without external multiplexing. Moreover, the onboard ADC converts each signal to 12-bit digital values for the controller. This design provides accurate process variable readings for monitoring and control loops.

Mechanical Integration and Mounting

You must insert the ABB Bailey IMRAI11 Analog Input 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 0.49 kilograms for straightforward handling. Furthermore, the two status LEDs indicate power presence and module health at a glance.

Environmental and Storage Guidelines

You should store this ABB Bailey IMRAI11 Analog Input 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 contains no moving parts, it requires zero regular maintenance over its service life.
