ABB Bailey IIPRT03 Network Module

The ABB Bailey IIPRT03 facilitates high-speed data exchange across Bailey control networks. This module uses a dual-port architecture for redundant communication paths. It weighs approximately 0.52 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 IIPRT03 includes two front-facing Ethernet ports for network connectivity. A single 48-pin backplane connector links this module to the host controller. This unit stores no energy internally because it lacks batteries. Three primary components form the complete assembly: the processor board, the faceplate, and the backplane interface.

Network Capabilities and Integration

The IIPRT03 supports both star and daisy-chain network topologies. You can configure this module for automatic failover when using redundant paths. For plant network integration, connect standard Cat5e cables to the RJ45 ports. The auto-negotiation feature selects the best speed for each link.

Installation and Operational Data

You can mount this module into any open slot of a Bailey INFI 90 rack. The module draws 250 mA from the 5V backplane supply during normal operation. Furthermore, it operates reliably within a 0°C to 60°C temperature range. Consequently, the IIPRT03 requires zero scheduled maintenance. Just check the LED status indicators during routine system inspections.
