The device EO-BAC is bidirectional gateway (it is both receiver and transmitter) between wireless EnOcean and BACnet MS/TP communication standards with the interface RS 485. Due to its construction, it is appropriate for installations in the suspended ceilings or underceilings spaces of buildings. It enables data receiving from up to 40 EnOcean elements which it automatically assigns to BACnet objects. The EO-BAC-Tool application ensures comprehensive administration of the gateway and EnOcean elements. Powering is with a DC power supply in the range 10-32V or alternating voltage source 24V AC. It is standardly supplied in 868 MHz version including short antenna, see the product picture. In case of customer request we are able to supply in 902 MHz version and different types of antenna.

Description

Gateway is open for all elements and every manufacturer who follows the EnOcean standard. It currently contains more than a hundred profiles listed in the EnOcean Alliance, of which we are a member and is still being expanded with newly emerging devices. 



External antenna on a 2m long cable with a magnetic base (optional accessories)

Antenna options. The strenght and coverage of the signal is appropriately distributed according to the choice of antenna. For common locations, the antenna that is part of the device's delivery is sufficient. For spaces with a higher attenuation of signal (e.g. in metal control cabinet) and for better gain properties, we recommend the antenna with a cable and a magnetic base (must be ordered).
