ABB Bailey IIPRT092 Digital Input Module

The ABB Bailey IIPRT092 reads discrete field signals from sensors and switches. This module monitors up to sixteen digital input channels simultaneously. It weighs approximately 0.54 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 IIPRT092 features sixteen opto-isolated digital input channels for noise immunity. A single 48-pin backplane connector interfaces this module with the host controller. This unit stores no energy internally because it lacks batteries or capacitors. Three main components form the complete assembly: the PCB, the faceplate, and the backplane interface.

Field Wiring and Signal Compatibility

You can connect dry contacts or NPN sensors directly to the IIPRT092. Each input channel includes a built-in LED indicator for visual status confirmation. For terminating field wiring, use external termination units like the NTDI01. The opto-isolation provides 1500V RMS isolation between field and logic sides.

Installation and Operational Data

You can mount this module into any open slot of a Bailey INFI 90 rack. The module draws 180 mA from the 5V backplane supply during normal operation. Furthermore, it operates reliably within a 0°C to 60°C temperature range. Consequently, the IIPRT092 requires zero scheduled maintenance. Just verify input LED states during routine system checks.
