ABB Bailey IMFAI01 Analog Input Module

The ABB Bailey IMFAI01 converts field analog signals into digital data for Bailey controllers. This module handles up to sixteen differential input channels simultaneously. It weighs approximately 0.55 kg and fits any standard Bailey rack slot. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.

Technical Specifications & Hardware Details

The IMFAI01 provides sixteen analog input channels with 12-bit resolution. A single front-face LED indicates the module’s power and operational status. Two ribbon cable headers connect this module to external termination units. This unit stores no energy internally because it lacks batteries or supercapacitors.

Installation and System Configuration

You can mount this module into any open slot of a Bailey INFI 90 rack. The IMFAI01 supports both voltage (0-10V) and current (4-20mA) input modes. For field wiring, connect this module to NTAI series termination units via ribbon cables. The configuration jumpers on the PCB determine each channel’s operating mode.

Operational Specifications

This module draws only 200 mA from the 5V backplane supply. It operates reliably within a 0°C to 60°C temperature range. Furthermore, the IMFAI01 withstands 5g vibration from 10 to 55 Hz. Consequently, this analog input module requires zero scheduled maintenance. Just inspect the ribbon cable connections during routine system checks.
