Flexible I/O expansion for OptiFlex™ BACnet building controllers
The OptiFlex™ I/O Expander FIO48u extends the input and output capacity of OptiFlex™ BACnet Building Controllers, providing a compact and scalable solution for expanding control capabilities within the WebCTRL® building automation system.
OptiFlex I/O expanders deliver input and output capacity to the powerful OptiFlex BACnet Building Controllers. Up to nine OptiFlex I/O expanders can be added to an OptiFlex BACnet Building controller.
OptiFlex I/O expanders are designed for flexible panel configurations. They are DIN rail or screwtab mountable and can be mixed and matched to meet the I/O requirements of the equipment being controlled. The expanders can be mounted directly to the OFBBC controller or remotely mounted up to 500’ away.
The FIO48u is compatible with the following OptiFlex™ BACnet Building Controller models:
OF1628
