ABB Bailey IOR-800 S800 Gateway

The ABB Bailey IOR-800 bridges Harmony S800 I/O stations to Bailey control networks. This gateway module manages data exchange between distributed field devices and the main controller. It weighs approximately 0.85 kg and occupies a single module slot. Its dimensions measure 27.9 cm in length, 12.7 cm in width, and 5.1 cm in height.

Technical Specifications & Hardware Details

The IOR-800 features two Ethernet ports for redundant network connectivity. A single backplane connector interfaces this gateway with the S800 I/O cluster. This unit stores configuration data in onboard non-volatile memory. Four main components form the complete assembly: the processor board, the faceplate, the backplane connector, and the status LEDs.

Network Integration and Redundancy

You can configure the IOR-800 for redundant network paths to ensure continuous operation. The dual Ethernet ports support automatic failover when one link fails. For system integration, connect this gateway to the main Bailey controller via standard Cat5e cables. The module also supports daisy-chaining multiple S800 stations together.

Installation and Operational Data

You can mount this gateway module into any Harmony S800 I/O station. The module draws 350 mA from the 24V DC field power supply. Furthermore, it operates reliably within a -20°C to 60°C temperature range. Consequently, the IOR-800 requires no battery replacement over its lifetime. Just check the LED status indicators during routine system inspections.
