ABB Bailey NIAI05 Termination Module

The ABB Bailey NIAI05 terminates field sensor signals for Bailey analog input systems. This module connects directly to analog input slave modules like the IMASI03 or IMASI13. It weighs approximately 0.6 kg and mounts on a standard DIN rail. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.

Technical Specifications & Hardware Details

The NIAI05 provides sixteen screw-type termination points for field wiring. A single ribbon cable interface connects this module to the host analog input module. This unit stores no internal energy because it lacks batteries or capacitors. Three main assemblies make up the entire module: the PCB, the terminal block, and the mounting base.

Installation and System Integration

You can install the NIAI05 inside any control cabinet with adequate airflow. This module requires no external power supply because it operates passively. For reliable signal transmission, use twisted-pair shielded wiring for each analog input. The ribbon cable carries all 16 signals directly to the host IMASI series module.

Field Wiring and Maintenance

Each termination point accepts wire gauges from 0.5 mm² to 2.5 mm². The screw terminals provide secure connections that resist vibration loosening. This module operates within a -20°C to 70°C temperature range. Consequently, the NIAI05 requires zero scheduled maintenance beyond routine visual inspections. Simply check terminal tightness during system shutdowns.
